| Abstract [eng] |
The increasing demand for sustainable bio renewable energy has led to three decades of intensive research on various biofuel cell technologies. Microbial fuel cells are believed to be the gold standard for recovering wastewater generated from industrial plants while simultaneously generating electricity. Although wide-spread application of these fuel cells, because of low electric production, has not happened yet. However, various new materials, methodologies, technologies, or microorganisms are researched to increase biofuel cell electrical yield, and conducting polymers is one of them. The research described in this work is associated with the modification of yeast cells Saccharomyces cerevisiae with conductive polymer polypyrrole or polydopamine. Further, the thesis describes unique methodologies how to achieve yeast cells covered with either polymer. The newly created biocomposites were characterized in detail with methods like atomic force microscopy or isotope ratio mass spectroscopy. Finally, yeast-polymer biocomposites were applied in microbial fuel cell designs with positive outcome. |
