The meeting in Miskolc, Hungary took place from October 14th to October 18th 2024. Working in internationally mixed groups we did a research about the production of bioethanol and tried to figure out pros and cons about the usage of bioethanol considering both ethical and economical aspects. Afterwards we had a debate on that issue. The experimental production of ethanol by fermentation, the measurement of the CO2 produced and the impact on different parameters on the reaction were done in internationally mixed groups. A visit to the life-science university with a lab workshop on different methods of purification gave us more insight into the different fields of biotechnology and ecology. The meeting was completed by an evaluation and reflection of the acquired knowledge and competences.

During this meeting we got a deeper insight into the enzymatic degradation of bioethanol out of cellulose and starch. We worked together in small groups measuring the glucose concentration with electronic test stripes. At the end we distilled the ethanol produced.

During the Erasmus+ 2025 week in Vienna we carried out experiments on the enzymatic degradation and fermentation of cellulose and starch in internationally mixed small groups. Thanks to presentations from students from Vienna, Hungary, Poland and India (online), we learned about the theoretical background of the experiment. After adding the enzymes cellulase and amylase respectively we measured the increasing concentration of glucose photometrically. As expected, an increase could be observed in every group. After adding yeast, the fermentation was measured by a decrease of the glucose concentration. The experiment was completed by an intense discussion of the results.
