Microbial fuel cells (MFCs) are bioelectrochemical devices that convert chemical energy into electrical energy from organic matter oxidation (fuel), utilizing microorganisms in bioanodes. Thus, this PhD project has the objective to study a biofuel cell using facultative anaerobic microorganisms (fungi specie Saccharomyces cerevisiae) for ethanol bioproduction, in which can be used as a substrate in other systems aimed at obtaining cooperative bioelectrodes in the presence of enzymes. For this, two conversion energy routes will be study: 1) release of reducing agents in solution; 2) electron transfer intracell membrane. In relation of the state-of-art for these systems, the biggest challenge is to develop robust bioelectrodes, with high electrochemical stability and high power density. Furthermore, the literature has few reports about electron transfer intracell membrane kinetics. Thus, principal objective of this project is overcome these challenges, proposing the utilization of bioanodes with modified flexible carbon fibers. Also, it is intended to study the mechanisms involving electron mediators and the bioelectrodes, as well as the comprehension how these microorganisms can be influence kinetic reactions. Lastly, it is intended to optimize MFCs prototypes in laboratory scale to obtain better operating conditions.
