The use of yeast surface display in biofuel cells

Abstract

Biofuel cells are electrochemical devices which convert chemical energy to electricity using biochemical pathways and redox enzymes. In enzymatic fuel cells purifi ed redox enzymes catalyze the reactions in the anode and cathode compartments whereas in microbial fuel cells (MFCs) the entire metabolism of the microorganisms is exploited. Here, a hybrid biofuel cell concept is presented, which is based on yeast surface display (YSD) of redox enzymes to catalyze the different cell reactions.
