Magda Kiernozek and Tomek Płudowski, Akademeia 13 Year students, alongside with Mateusz Gabor, our gap year student (a future student of Chemistry and Molecular Engineering at University of Chicago), participated in the E(x)plory science conference. They have been working on an interdisciplinary project which covered the areas from chemistry, biology and engineering.
E(x)plory is the unprecedented event for young people (aged between 13 and 20) who are passionate about science. It is a great feast of science from all around the world, where young scientists meet their colleagues who share the same interests, and have opportunity to share their ideas and projects to academics and scholars, business representatives and new technology creators.
Regional E(x)plory Science Festivals are regional scientific conferences attracting participants through popularizing science and new technologies in an innovative way.
In the first stage, our young scientists submitted a project which was selected as one of the best-submitted projects and went to the regional stage. The students worked and developed intensively onwards on their project resulting in a poster which was presented on the regional scientific conference in Łódź.
The project was based on the study of rates of the fermentation process of white sugar in the presence of metal ions in the acetate buffer. Students used carbon dioxide (CO2) sensor to follow the progress of fermentation, and two more additional sensors to control changes in temperature and pH in the system. By performing the spectrum of reactions (100 experiments) and multifactorial treatments, and based on observations, data and statistical analysis, they were able to propose two hypotheses which grasped the interest of the jury on the scientific conference. Hypotheses described the effects of metal ions on cell (yeasts) respiration, in particular, the ability of yeast cultures to perform a facultative change between aerobic (in the presence of oxygen) and anaerobic (in the absence of oxygen) respiration.
