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) was used in MFCs in several earlier examples and was proven to be an efficient catalyst in such devices (with or without the use of external mediators). A biofuel cell containing bacteria at the anode and laccase as the reducing enzyme for oxygen
reduction at the cathode was recently demonstrated.
