"I conducted the characterization of the solubility of the obtained lignin in various solvents"

Karel Fous from Czech Republic, Period of Erasmus+ internship: October - December 2022.

I have decided to come to Luleå through the Erasmus+ student exchange program as a part of my work on my master's thesis within the study program of Biotechnology and Bioengineering at the University of Chemistry and Technology in Prague. I had the opportunity to complete an internship at the Biochemical Process Engineering department and to be closely involved in the preparation of coatings with antifouling properties.

During the internship, I learned how to extract lignin from wood and separate its other components. Subsequently, I conducted the characterization of the solubility of the obtained lignin in various solvents. The acquired lignin was then used for producing coatings with antifouling properties, which I tested at my university in Prague using different bacteria. I also determined the contact angles of the coatings with demineralized water.

The working environment in the laboratory was incredibly friendly and pleasant. Each member of the lab was supportive, and willing to help. Collaborating with people from various parts of the world was inspiring and encouraging. I believe that some of the strong friendships formed in Luleå will endure a lifetime and will develop both in professional and personal life. The opportunity to work with esteemed researchers significantly enriched my knowledge in the field of chemical engneering and bioengineering.

Living in a city so close to the North Pole is mindblowing. Experiencing nearly polar nights, temperatures around -20°C, and widespread snowdrifts for a few months is a lifelong experience. Observing the enchanting Northern lights, walking on frozen sea, dipping in frozen lake and encountering moose and reindeer are common experiences in Luleå that I will remember forever.

"I had the opportunity to work in the Biochemical Process Engineering group"

Kyriakos Antoniadis from Greece, Period of Erasmus+ internship: October 2022 - March 2023.

After my graduation I came to Luleå University of Technology through the Erasmus+ student exchange program, as a master graduate from the Department of Biological Applications and Technology at University of Ioannina (UoI). I had the opportunity to work in the Biochemical Process Engineering group and do a 6-month internship to further expand my experience and knowledge as well as engage with the international scientific community.

During my internship, my main project involved working with microalgae and marine thraustochytrid species for the production of omega-3 fatty acids. For that reason, I did significant research on the cultivation techniques of these microorganisms. Moreover, I obtained hands-on experience on various analytical techniques, such as GC-MS/FID and HPLC- RI/UV as well as worked with large scale experiments with the help of bioreactors. All these were made possible with the careful and professional guidance of my supervisors but also through meaningful collaboration with all the members of the laboratory. I was able to engage with others during meetings or brainstorming sessions to a most wholesome experience.

The excitement didn’t stop in the lab as the city’s beauty further complimented my experience. White scenery as far as the eye could see and the accompanying low temperatures reaching as low as -25 oC. However, where else could I have walked on the frozen sea and barbequed on a frozen island or walked in the city doing cross-country ski? All these were memorable experiences that made my stay in Luleå priceless and made it a definite return destination in the future.

"My collaboration with my supervisor and the rest members of the lab was excellent"

Evangelos Sarmas from Greece, Period of Erasmus+ internship: February - May 2023.

I came to LTU for a four-month internship as a recent graduate of the biology department of UOC through the Erasmus+ student exchange program. The reason why I chose to do my internship in the Biochemical Process Engineering group was my interest and curiosity in the innovative studies that are carried out by this group in the field of biotechnology.

During my internship, I worked on carbonic anhydrase production and purification from different origins in order to capture CO2 from industrial off gas as part of the VIVALDI project. My collaboration with my supervisor and the rest members of the lab was excellent. I learned a lot of techniques related to enzyme production and I got familiar with assays about enzyme characterization (detection and quantification of enzymatic activity). Also, I learned to set up CO2 capture experiments on a small scale. Despite my lab skills, I improved my soft skills too. For instance, I learn to manage my time better and to communicate in English. Overall, I became more confident, independent, and productive in my work.

The lifestyle in Lulea was extraordinary and different from the lifestyle that Ι am used to. I had the opportunity to gain experiences and make memories that I will remember for the rest of my life. Some of them are that I saw the Aurora, went hiking in the snow, fed mosses, and walked in frozen lakes and seas. Last but not least, the most important from the whole experience is that I met people from different places of the world with a different mindset that I wouldn't have the opportunity to meet otherwise and develop special bonds with them.

I had the opportunity to do my internship at the Biochemical Process Engineering and to do my bachelor’s thesis on the co- immobilization of enzymes for efficient hydrolysis of pretreated biomass residues. During the traineeship, I learned to immobilize cellulases as cross- linked aggregates (CLEAs) and as magnetic cross- linked aggregates (m-CLEAs) and then I proceed to the characterization of the obtained immobilized enzymes and the optimization of the immobilization conditions. Finally, the immobilized enzymes were used for hydrolysis of pretreated biomass residues.

The working environment at the laboratory was so warm and pleasant. All the members of the lab were very friendly, caring and willing to help you. Working with people from all around the world was so motivating and exciting. Moreover, having the chance to work with so many distinguished researchers offered me the opportunity to expand my knowledge in the field of biotechnology.

When it comes to Luleå city, there are really no words to describe this wonderful place. Living in a city so close to the North Pole is so fascinating. Experiencing the magical Northern lights, walking on the frozen lakes and sea, and feeding muses and reindeers are considered “normal” stuff for Luleå. Ice- skating, cross- country or downhill skiing and hiking are some of the activities that you can enjoy. Last but not least, you will have the pleasure to meet little squirrels and rabbits everywhere, especially around the campus of the university.

"Experiencing subarctic climate was also new to me and quite exciting"

Eric Nabil Risse from Switzerland, Period of IAESTE internship: October 2021 – June 2022.

Visiting Sweden was something I wanted to do for a long time. I did my IAESTE internship from October 2021 to June 2022. Nine months during which I had the chance to witness the unusual weather, beautiful colours and landscapes, to meet interesting scientists and people, within and outside the Luleå University of Technology, and experience nice and warm traditions, that punctuated my stay in Sweden.

The academic environment of the Luleå University of Technology is rich and dynamic. Coming from the field of microbiology, I had the chance to work with various microorganisms and see first-hand how their metabolic properties could be exploited in the field of biotechnology, to answer the needs of our societies, from pharmaceutical to industrial fields. Studying those organisms from the point of view of biochemistry taught me a lot and enriched my approach as a biologist, broadening my understanding and my experience, pushing me to go out of my comfort zone and to develop a multidisciplinary mindset. Working at the Luleå University of Technology offered me the opportunity to experiment analytical and scientific techniques I have never worked with before, all the while collaborating with scientists from different backgrounds, diverse cultures and various countries.

Experiencing subarctic climate was also new to me and quite exciting: long and dark cold winters with thick layers of ice and snow that allow you to walk on the frozen sea, short days with colourful and bright sunsets, turning into a short spring/summer with almost never-ending days for two or three months. you may find it disturbing the first time, but fear not: it did not deter people from outside Sweden to stay here for a few years or even more.. Regularly I went walking on the frozen water, simply to enjoy the feeling and catch some sunlight during my free time or went outside Luleå to see the surroundings. I met people from a wide range of countries, learned about their cultures and their background. I enjoyed my time in this multicultural environment, with people coming and leaving. I also had the chance to spend some time with Swedes, that introduced me to their country and its customs.

Overall, it was an enriching experience, that allowed me to grow both as a human and as a scientist.

"Contributing to the work of this research group felt very motivating"

Elena Hui from Switzerland, Period of IAESET internship: February – June 2022.

From February to June 2022, I had the opportunity to work as an IAESTE intern in the biochemical process engineering department of Luleå University of Technology. As a biology student, I appreciated the chance to extend my knowledge beyond the boundaries of my discipline by experiencing the daily routine of a chemical and biotechnology laboratory focusing on the sustainable production of nutrients, chemicals and medical substances with industrial applications. More concretely, I worked on the valorisation and modification of some bioactive substances contained in a halophyte plant by means of enzymatic synthesis. The daily work in the lab and the use of sophisticated machinery such as the High-performance liquid chromatography (HPLC) that I operated regularly allowed me to acquire a great deal of autonomy and confidence. Participating in and contributing to the work of this research group felt very motivating: I appreciated a lot its multicultural environment, the great variety of its projects and the focus on the applicability of its research in real world settings.

Besides being a professionally enriching experience, my stay in Sweden taught me many other things. Not least, I learnt how to withstand arctic temperatures approaching - 30°C and how to sleep with light during summer. Located in the north of Sweden just a few kilometres from the Arctic Circle, the small town of Luleå allows in fact to witness the incredible changing of the seasons in Swedish Lapland. I remember with joy a winter walk on cross-country skis on the frozen sea of Luleå that ended under some beautiful northern lights, as well as a summer hike in Abisko National Park accompanied by the spectacle of the midnight sun. From Luleå I had the opportunity to visit also many other places including the lovely Swedish capital and Norway's amazing Lofoten islands. In summary, I am extremely grateful for the opportunity I had, for everything I learned and for all the people I met during this time. I would particularly like to thank all the people in the lab, the IAESTE committee and the gymnastics group that I joined during these months (Lulegymnasterna) for making this experience not only possible, but also unforgettable.

"During my internship I discovered the highly promising field of biotechnology"

Eleni Kapidou from Greece, Period of IAESTE internship: May 2021 – February 2022.

After finishing my bachelor studies in Chemistry, I applied for an internship at Luleå University of Technology. Throughout my internship in the Biochemical Process Engineering department, I worked with enzymatic reactions for the modification of natural compounds from a halophyte. These naturally occurring compounds were phenolic acids, which in general exhibit strong biological properties. Therefore, the purpose of my research was the valorisation and the biological enhancement of these compounds through enzymatic trans-esterification reactions. Through this internship I had the opportunity to improve and learn new laboratory skills and develop my academic writing. Working with highly experienced researchers helped me think as a researcher regarding the optimization of experiments and problem solving.

By the time I arrived, I met wonderful people both in the IAESTE LC and in the laboratory who made my experience in Luleå unforgettable. The multicultural group in the lab is very supportive, willing to help you and discuss about their projects, which helped me broaden my knowledge in different aspects of biotechnology, and what’s more, they are the cherry on top of the cake regarding my Luleå experience.

Living in the Swedish Lapland all you can talk about is the extraordinary nature. Living here for 9 months gave me the opportunity to experience from the midnight sun where the night is an infinite sunset to the northern lights which make the cold dark winter looks like a fairytale. The daily life is completely different comparing to what other places offer. Hiking becomes more fascinating in combination with berry picking and aurora hunting. Last but not least, ice skating turns into a routine during the winter months.

During my internship I discovered the highly promising field of biotechnology. I realized how I enjoy working abroad with people from all over the world. Working in the field of research played a decisive role in my thoughts regarding my future career as it is challenging, and it helps develop and discover new things every day. Therefore, now I am applying for Master’s programs in Sweden due to the numerous opportunities in the field of biochemistry and biotechnology that are offered. Not to mention, Sweden offers the ideal working environment as it combines respect between each other, orderliness and of course a lot of FIKAS!

"In the laboratory I had the opportunity to work on pioneering experiments"

Irene Delgado Vellosillo from Spain, Period of IAESTE internship: August 2020 – August 2021.

I chose Luleå as the destination to do my first internship for 6 months after finishing my bachelor degree and I ended up staying for 1 year because of the incredible experience it was.

In the laboratory I had the opportunity to work on pioneering experiments with microalgae that allowed me to develop my skills in the laboratory and my first steps working by myself. The department has several research groups made up of wonderful people who end up being your family and it is a pleasure to work with them.

The city of Luleå is a unique place. The nature that surrounds it makes it the ideal place for sports and adventures in nature. The weather is what most craters this city, being able to enjoy the northern lights every winter night and landscapes covered by meters of snow as well as being able to skate on the sea or the lake to cross to the supermarket. However, in summer you lose track of time with dusk-dawn at midnight, since there is no night all summer.

"I had an amazing time"

Clara Homor from France, Period of ERASMUS project work: September – December 2020.

I chose Luleå as my Erasmus+ destination from september 2020 to december 2020 and had an amazing time.

The road trip weekends with friends, the hikes in the middle of nowhere, the barbucue by the sea was great and even the cold was appreciated with temperatures sometimes below 0. I stayed 4 months and it was not enough to discover everything. I am looking forward to go back. Everything was exceptional and unique; at the end of the year when the night comes around noon and the northern lights appear, it's magical.

At the same time as my classes, I had the opportunity to work on a project in the biochemical process laboratory at Luleå University. It was about CO2 capture. I worked on the characterization of the enzyme and on finding the optimal conditions. It was a very interesting project with important applications for the future. The people in the lab are very friendly and welcoming, I was glad to join the team to work with them.

Currently, I am still studying in the field of energy, adding some skills in economics, to assist companies in their energy transition.

"I can say the whole experience was very pleasant"       

Ayanne De Oliveira Maciel from Brazil, Period of IAESTE internship: October 2019 - April 2021.

I worked as IAESTE intern in Luleå University of Technology for almost one and half year and it was a very interesting experience. Before coming to Sweden, I was coordinating engineering projects in Brazil, so becoming again an intern after almost 8 years of completing my engineer degree was something unique. I was looking for an opportunity to transit from the industry to academia, so the internship could provide me a great opportunity to learn several techniques in research. Furthermore, after finishing the intern program, I could apply for a PhD position in the same department and now I am pursuing my doctorate studies in CO2 capture. The work environment in Luleå University of Technology is full of young and helpful colleagues, what made my experience smoother.

In my free time, I could enjoy a bit of attractive of the northern part of Sweden. Luleå is a very pleasant place, where weather extremes happen - and this is exactly why is so distinctive. If the cold and snow are present for a long time over the year, the sun is infinite during the summer. The Lapland region has a lot of beautiful landscapes and people are very sympathetic. It us fun to say, but I strongly recommend trying the outdoor lifestyle Swedes do – from the hiking trails to the ice skating and Nordic skiing in the middle of the sea.

Finally, I can say the whole experience was very pleasant and one of the most different I did in my life: I recommend very much for the ones who are not afraid of something completely new.

"I finally had the opportunity to walk at least part of Kungsleden Trail"

Dominik Maršík from Czech Republic, Period of ERASMUS internship: August – November 2021.

I came to Luleå University of Technology for a four-month internship as a doctoral student. The first thing that pleasantly surprised me as a student from Prague was the environment in which the university is located. Sweden is generally known for its beautiful nature and at Luleå University of Technology you can literally enjoy it on a regular daily way to school. My internship was scheduled from August to December so I could enjoy the remnants of summer, colourful fall, and the beginning of winter. I cannot decide which season was nicer, you need to experience them all. Even though the days are getting shorter with upcoming winter season, the loss of light will be compensated by an impressive play of lights in the form of aurora borealis.

As a lover of tourism, I appreciated the location of Lulea, from which it is easy to reach Abisko National Park or Norwegian Lofoten. I finally had the opportunity to walk at least part of Kungsleden Trail. Beautiful trips to nature could also be taken around Luleå. There are many hiking trails around that you could enjoy to the fullest. We have always lighted up our trip by barbeque in beautiful rest areas or by picking blueberries, lingonberries, and mushrooms.

Culturally, life in the north is in some aspects different from life in Central Europe. In general, the Swedish were very kind and helpful, and after several years of living in the big city, the peace and serenity of the Luleå citizens was a pleasant change. The experience of working in the international group of Biochemical Process Engineering was also priceless. The different experiences of lab colleagues, who have soon become friends, were beneficial both professionally and personally. I am writing this report just before leaving to Czech and I regret that I only had the internship scheduled for four months. My big wish now is to maintain our newly established cooperation and friendships so that I can return to Luleå University of Technology in the future.

"I hope that the established friendships will last"

Markéta Kulišová from Czech Republic, Period of ERASMUS internship: August – November 2021.

I went to Luleå University of Technology as part of an internship during my doctoral studies in Biotechnology field. After the initial surprise, that I was actually going to live near the Arctic Circle, I began to look forward to what new experiences I would encounter during my stay in Sweden.

The nature in and around Luleå is absolutely surreal. Here you could find many forests, where you can collect a variety of berries and mushrooms (of which there is an incredible number, because Swedes are not big fans of mushroom hunting). There is also a lake on every corner, where it is possible to try kayaking in summer or endless ice skating in winter. Almost everyday thing for me was admiring breath-taking sunsets, which you will especially appreciate with the coming winter season, when it is getting dark outside very soon. And if you receive northern lights alert on your phone, you go out hunting for them, and as soon as you stand in front of your house, you see the incredible beauty with your own eyes, you know, that you want to return to this city in the future.

The university itself is very well equipped and the work in the laboratory of Biochemical Process Engineering has been very enriching in many aspects. As the main positive experience, I have to pinpoint possibility to work in an international team of researchers. I had the opportunity to work with people from many different cultures, languages and approaches to science for the first time in my life and it was priceless experience. Everyone was incredibly helpful, whether my questions were about working in the lab or even everyday practical issues. Swedish fika, which often included a cake baked by a laboratory colleague, was just the icing on the cake of the days spent in the lab.

In short, the internship at Luleå University of Technology has brought me many beneficial experiences for my future professional and personal life. I hope that the established friendships with co-workers in the laboratory and the cooperation of my home university in Czech Republic with Luleå University of Technology will last as long as possible.

"The people working in the lab are another gem stone embellishing the Luleå experience"

Kalliopi Elli Pavlopoulou from Greece, Period of ERASMUS: July – September 2021.

My decision to visit Luleå as an intern was one of the best I ever made! I took part in a mineral processing project, a subject that I didn’t have any knowledge on before this summer. Finishing my internship, I must admit I gained a lot of knowing not only in minerals, but in the whole treating process of residual forest biomass, from the first stages of organosolv process up to producing nanoparticles from the isolated lignin. It was a very interesting journey and a unique opportunity to see up close procedures that we learn only theoretically in courses or read in articles for projects.

“My time in Luleå was full of new experiences”

Eleftheria Sapountzaki from Greece, Period of ERASMUS: January – August 2021.

I came to Luleå through the Erasmus+ student exchange program, as part of my studies in chemical engineering at NTUA. I had the chance to work in the Biochemical Process Engineering group of Luleå University of Technology, to do my master’s thesis on the evaluation of phytochemicals from a halophyte extract for their antiviral potential, through molecular docking simulation and enzymatic assay. Moreover, I also had the chance to work on the enzymatic functionalization of hydroxycinnamic acids.

"I also learned how to deal with microbial cultures"

Eleni Krikigianni from Greece, Period of ERASMUS: January 2018 – June 2018. Period of IAESTE: October 2018 – June 2019

My first experience in the Biochemical Process Engineering group was as an Erasmus student for the final thesis of my degree as a Chemical Engineer at NTUA, Greece, with a special interest in Biotechnology. During those six months I realized that I enjoyed a lot working in a lab surrounded by incredibly supportive people, but also the involvement in a project with real-world applications strengthened my interest in research. Due to that, and for the fact that Luleå offers a completely different experience over the seasons, I gladly extended my stay as an IAESTE intern for another nine months.

During all that time I participated in the production of food-grade oligosaccharides with high prebiotic value from forest, but also marine biomass. I became familiar with several laboratory techniques such as enzymatic production, biomass saccharification, product recovery and purification with pressure-driven membrane methods and scale-up processes. I also learned how to deal with microbial cultures, both in aerobic and anaerobic environments, and how to use chromatographic instruments. Most importantly, I learned how to work independently under great supervision and I broadened my knowledge about different scientific topics. The multinational environment of the lab was just perfect to share experiences and knowledge. After I finished my internship I applied for a Research Engineer position and I am currently starting my PhD at the Biochemical Process Engineering group.

Luleå offers an unforgettable experience that you can only get the chance to live in the north of Sweden. Northern lights brighten the long dark winter but during the summer months the almost 24 hour sun makes up for the darkness. During winter you get the chance to walk, ski, skate, or even drive on the frozen sea and if you feel more adventurous you can hike with snowshoes in the deep forest and stay in one of the many free cabins overnight under the warmth of a fire stove. If you are a ski enthusiast and you are able to rent a car you can find some nice slopes closeby. You can also visit the ice hotel in Kiruna or the Arctic moose farm or the Santa Claus village in Rovaniemi, Finland. During summer the possibilities for hiking in Luleå but also in nearby places are endless and so are the biking paths. There are boats that you can take to visit the nearest islands in the Luleå archipelago but you can also rent a canoe or a kayak and explore the rivers around. Although it might not be that close I definetely suggest a visit to the Lofoten islands in Norway and the Abisko national park in Sweden.

Overall, if you like nature and wilderness then Luleå is the place to be!

"It is impossible to guess how late it just by sun position"

Stephan Liefeldt from Germany, Period of ERASMUS: May 2019 – November 2019

I came up in the high north of Europe to learn more about getting eatable oil from fermented waste by using microorganisms. But I got so much more: new friends, memories and a taste of the Swedish was of living. In the lab, I cultivated different algae strains by using various organic acids as an carbon source to see, how they can utilize them. It was a relaxed atmosphere at the chair and I got all the help I needed when I asked for it.

Outside of the lab, I met a lot of awesome people in this nice city, even if there are only 2.5 people per square kilometer. I really can recommend the student sport section (StiL) of the university. I took several activities there like hiking through the beautifully Swedish nature together with others in a guided tour or just borrowed some equipment there and went for a trip on my own. Also the Underwater rugby section of StiL is totally worth a try) And if you ask me, the best way to socialise is to visit Luleå Bugg och Swing and catch a dance.

But the most important rule up her is: Don’t trust your feeling about time! It is impossible to guess how late it just by sun position. In the summer, there is no big difference between 3 A.M. and 3 P.M. as the sun goes down but it never gets dark. In the autumn, you want to go home as it is already pitch-black outside. But it’s no later than 3 P.M.

I’ll always keep my time in Luleå in a good memory and my experience up there was one of the reasons, why I applied for a job in Sweden after I finished my Master’s Thesis.

"Living so close to the North Pole is astonishing"

Maxwel Moncao from Brazil. Period of IAESTE internship: October 2019 – September 2020

My experience as an intern in the Biochemical Process Engineering group was remarkable. I worked in two distinct projects: the fractionation and valorisation of agricultural and paper-and-pulp industry by-products for the production of biofuels, prebiotics and biogas; and with microalgae cultivation for proteins production with nutraceutical application. Through the internship I was given a lot of autonomy on experiments plan and development and I learned how to use multiple laboratory equipment.

Living so close to the North Pole is astonishing, the temperatures are negative during most of the year, the days are very short in the beginning of the winter and for over three months of the summer there are no nights and since there’s a lot of nature in and around the city of Luleå, there are always nice activities to join.

After my internship I applied for a Research Engineer position at Biochemical Process Engineering group and currently I’m planning on starting a PhD at Luleå University of Technology.

"Living in Luleå made me grow both professionally and personally"

Sergio Jurado Pedrajas from Spain. Period of ERASMUS: January 2019 – May 2019.

During my stay in Luleå, I was performing my master thesis. I worked on the organosolv fractionation of residual wood biomass (spruce bark), where the final goal was to study the use of the cellulose fractions as raw material for the production of methane by performing BMP (biochemical methane potential). Moreover, I studied the enzymatic saccharification potentials of the cellulose fractions that I recovered to study their potential to be used in bioproprocesses. Even not having experience in this topic, I felt really comfortable with all the people in the department and they help me always I needed it.

Luleå is an incredible spot where you can find two different worlds depending on the season. Northern lights, a frozen sea or a never-ending days are just some examples of what you can enjoy there. Apart from this, travelling with LURC, you will discover other wonderful places like Lofoten Islands, San Petersburg or Tallin.

Living in Luleå made me grow both professionally and personally. After one year in Luleä, I found a job working as industrial engineer and I realized the importance of living abroad, connecting with an international environment and meeting new people and cultures.

"The general atmosphere in the lab was very relaxed"

Milena Gerber studied biology at ETH Zürich in Switzerland.

I studied biology at ETH Zürich in Switzerland, majoring in biochemistry. During my Master's Thesis I was looking for an internship to start after my graduation and came across the work offer at Luleå University of Technology on the IAESTE platform. During my stay I had the chance to work on two main projects. The first was about the production of a dry lignin nanoparticle powder and optimising the protocol to achieve the smallest possible size of those particles. The second project concerned the treatment of mining wastewaters and more specifically the recovery of valuable metals in the form of metal nanoparticles, preventing their disposal into the environment. Another side project included organosolv pretreatment of forest biomass, followed by the characterization of all compounds. For those projects, I had to step outside my comfort zone sometimes, for example while operating a huge organosolv reactor. Nevertheless, I appreciated that people in the lab and especially my supervisor put a lot of trust in me and let me work independently most of the time. Like that I got hands-on experience in preparing samples for scanning electron microscopy and Raman laser spectroscopy, and learned various new techniques. Besides that, I improved my general lab skills and widened my knowledge about biotechnology and bioprocess engineering. The general atmosphere in the lab was very relaxed and it was fun to work in a multinational team with people of different scientific backgrounds. Having discussions with the other group members allowed me to develop a different way of thinking, which helped me to approach tasks and solve problems differently than I was used to as a biologist. I could be sure to get help and advice from anyone whenever I asked for it.

I also really enjoyed living in the small town of Luleå, where I felt welcome from the first day (which was also thanks to the friendly people from IAESTE and in the lab). I was lucky to experience the dark and freezing cold winter months where I went cross-country skiing and ice-skating on the frozen sea, and later the bright summer when the sun never sets. As a climber I enjoyed this part of the year especially, as there are many beautiful climbing spots close to the city. I am sure I will return to this amazing place to visit all the good friends I made here.

"I had the opportunity to be involved in the whole value chain of the process"

Kateřina Hrůzová from The Czech Republic
Period of IAESTE internship: September 2017 – February 2019

During my internship, my main project was focused on the production of the second-generation bioethanol from marine filter feeder – Ciona intestinalis. I had the opportunity to be involved in the whole value chain of the process: Starting with the organosolv pretreatment of the marine biomass, its fractionation and characterization, followed by the enzymatic hydrolysis and fermentation. I have learnt various new techniques and I have handled numerous laboratory equipment. In addition, I participated in many other projects, such as the pretreatment of the forest biomass and its enzymatic hydrolysis - and subsequently, using these hydrolysates for bacterial rhamnolipid and algal lipid production. Moreover, I operated a pilot scale industrial equipment. I have learnt to work independently with a great supervision because there is an amazing team of people who are always keen to teach you and to help you whenever you need it.

Luleå is a lovely city surrounded by breathtaking nature and with a unique cycle of the year with icy dark winters and endless bright days in the summer. If you like sports, you can buy cheap second-hand equipment – and there are many places to go. The student organisation LURC is providing trips to Saint Peterburg, Helsinki, Lofoten, Arctic moose farm, and a Sea battle event when you can visit Stockholm and Riga, so you can also travel around quite easily.

When I finished my internship, I applied for a Research Engineer position at LTU and I plan to start a PhD studies at LTU in the future. I must admit that I fell in love with Luleå as a town and I appreciate the Swedish way of work and the great team of people I have the opportunity to work with.

"All in all, the internship at LTU was one of my best experiences I have ever made"

Saskja Bühler from Switzerland
IAESTE internship July 2018 – March 2019

After finishing my master programme in molecular health science at ETH Zurich I was looking for a working experience abroad and found this IAESTE internship up north. They introduced me well into the rather unfamiliar biotechnology field and I quickly felt comfortable working in the lab. The team was great and I really enjoyed the independent way of working with the knowledge that I can ask for help and support whenever I needed it. My project focused on the production of cellobiose, a prebiotic candidate, by optimised enzymatic hydrolysis of pretreated biomass and the scale-up of this cellobiose production. My research experience broadened a lot due to the different aspects of the main project and due to diverse side jobs like cultivation of various microorganisms and enzyme production.

Luleå is a great town for living and working and a very good starting point for trips to Norway and Finland. We even went once to St. Petersburg and Helsinki. The area in Luleå is beautiful with all those lakes, the sea and forest. Experiencing summer and winter in Luleå is
almost a must as everything looks so different. In summer you can explore the surroundings by boat, bike or foot and enjoy the never-ending daylight. In winter the piles of snow, frozen sea, freezing temperatures and especially the northern lights are amazing.

All in all, the internship at LTU was one of my best experiences I have ever made.

"I got to live in the north pole"

Dimitrios Vlasopoulos, Greece
Erasmus: January 2018 – June 2018
IAESTE internship: October 2018 – December 2018.

I started at Luleå University of Technology by doing my diploma thesis via the Erasmus program and then worked on the same project as an IAESTE intern. The project I worked on was about biocatalytic methods of CO2 absorption. My love for biotechnology and the environment made it even more of pleasure working on that project. I also had the chance to learn about different methods and equipment.

The whole experience was fulfilled by the unique chance I got to live in the north pole at -20oC and enjoy the northern lights always accompanied by my new friends.

"Moving to Sweden made it even more of an adventure"

Fabio Mikes, Switzerland
Period of internship: March – June 2018

At the time of my internship, I was studying Pharmaceutical Sciences at ETH Zurich, Switzerland. My 4-month internship at LTU focused on completely different subjects, but it was exciting to explore new research topics. And moving to Sweden made it even more of an adventure.

During my time as a member of the research group in biochemical process engineering, I was given the opportunity to work on multiple projects. My main task was to isolate lignin from different wood types and to explore novel applications. Besides that, I helped others with their projects and for example used microorganisms for sugar hydrolysis and lipid production. With literature research, experiment planning and execution, the lab work was a great opportunity to learn new skills and to experience the interesting world of academic research.

Luleå is a very small city, but there were still quite some things to do. In the earlier months of my stay, I liked to go skating on the ice road, practice with LTU’s student ice hockey team or go watch the professionals play at Coop Arena. Once the snow started melting, I went for bike tours to Gammelstad, the old town of Luleå, or had barbeques at one of Lulea’s countless beaches. Interns are also invited to be part of the exchange student network at LTU, allowing you to meet more people and to participate in many fun activities (e.g. a city trip to Helsinki and St. Petersburg in my case).

All in all, it was a great experience to live and work in Luleå. New friendships as well as the amazing support by colleagues and supervisors made my time in the north even more enjoyable.

"Living in Luleå was incomparable to anything I have done before"

James Wright Aspden, UK
Period of internship: October 2017 - February 2018

Before coming to Luleå, I studied Biochemistry and Microbiology at the University of Strathclyde, Glasgow. Through IAESTE I gained this internship for a period of 5 months focussing on Organosolv pretreatment and Fermentation of Beechwood. This project allowed me to experience working in a field closely related to mine, giving me an insight into many Biotechnology techniques and alternative career possibilities. I found the work interesting and the other lab members were always friendly and willing to help if they could. Their positive attitude and enthusiasm towards their research was infectious meaning my time here did not feel like work at all.

Living in Lulea was incomparable to anything I have done before; seeing the Northern Lights; going dog sledding and skating on the frozen sea are experiences I will always remember. There were a lot of excursions organised and learning to play ice hockey really enhanced my experience, allowing me to meet other students in Lulea from all over the world.

After my internship at LTU I am moving to Germany for a placement in Greifswald. Thereafter I hope to continue with my studies and pursue a Masters. This internship has provided me with excellent laboratory experience and taught me techniques I will undoubtedly use in the future, enhancing my career prospects.

"The environment in the lab was really nice"

Meritxell Blas, Spain
Period of internship: February-June 2018

My experience at Luleå University of Technology has been really satisfactory. My project was about ethanol production from CO2 by Sporomusa ovata via microbial electrosynthesis. I still remember the first time I entered the lab and saw how big it was and how many equipment they had. And I thought I would do a good job here. The environment in the lab was really nice, all the interns were so close to me and we connect since the beginning. My supervisors gave me a lot of freedom in the lab, but they were always there if I had any doubt.

"It was a great experience which offered me valuable knowledge in the field of biotechnology"

Alexandra Gerogianni, Greece
Period of internship: October 2016-June 2017

My experience at Luleå University of Technology started with an internship in the terms of the Erasmus placement program and then I continued my work there as an IAESTE intern. During the time I spent in Biochemical Process Engineering group, I had the chance to be involved in three different projects; the production and purification of LPMO enzymes, the characterization of FoFaeC mutants and the production of L- arginine by E. coli mutants. I became familiar with cultivations, fermentations in bioreactors, various techniques of analysis and downstream processing.

Moreover, through this internship I became able to manage different projects, work independently but also collaborate and conduct real research. In overall, it was a great experience which offered me valuable knowledge in the field of biotechnology and helped me in my future steps. Currently, I am doing my Master studies in Biotechnology at Lund University.

"Currently, I am doing my PhD at the technical university of Vienna"

Katharina Novak, Austria
Period of internship: November 2015 - June 2016

During my studies of biotechnology in Vienna, Austria I got the great opportunity to do an internship at LTU. From the beginning I was really excited, since Sweden was always a dream destination for me. Since have not had any prior knowledge on the topic of my research field, I gained a lot of experience during my research stay. The project dealt with the production of biofuels from wood hydrolysates with both algae and yeasts. The things I appreciated most was on one hand the intensive supervision by my tutor and on the other hand the lovely atmosphere I came in. The other PhDs let me participate in all their activities and considered me as part of the group, although I did not stay for too long. I still think back of that with a smile on my face.

After my internship, I wrote my master thesis about my research done at LTU and finished my master’s degree in Vienna. Currently, I am doing my PhD at the technical university of Vienna in the field of biochemical engineering. The experience at LTU gave me some good inputs for my current work.

"My project was focused on increasing the value of forest products and residual waste"

Olga Yakimenko, IAESTE intern from Kazakhstan
Period of internship: September 2016 – May 2017

The research internship at Luleå University of Technology offered me a great opportunity to obtain a real valuable experience of working in the field of biotechnology and process design. This research is a special chance for me because my special field of interest is about developing integrated processes that combine biotechnology and chemistry to produce foods, chemicals and fuels.

My project was focused on increasing the value of forest products and residual waste; we’ve worked to develop and demonstrate the production of biogas, methane from forest products and a high quality biochar from lignin. Even though it's quite far from what I did previously, this experience’s certainly broadened my skills in molecular techniques which are applicable for future studies and research furthermore faced me with challenges, process of learning and overcoming difficulties that I enjoyed.

After completing my internship at LTU I went to Taiwan as a participant of TIGP-International Internship Program in Interdisciplinary neuroscience track, which dragged my interest in biomedical research. Currently I’m Master’s program student in Biomedicine at Karolinska Institutet in Stockholm.
