Surface Display of Redox Enzymes in Microbial Fuel Cells

Enzyme-based biofuel cells utilize purified enzymes as catalysts for the oxidation/reduction of metabolites at the anode or cathode, respectively, at room temperature. Microbial-based fuel cells (MFCs), however, exploit the metabolism of an entire organism for catalyzing the oxidation of fuels, ranging from glucose and ethanol to starch and cellulose. Saccharomyces cereVisiae (S.cereVisiae) wa…
