Geobacter sulfurreducens possesses the ability to directly transfer electrons to anodes of microbial fuel cells without addition of soluble redox mediators. This property allows for growth of high current-density generating biofilms supplying uninterrupted power from complete oxidation of acetate. We have recently reported qualitative modeling of the catalytic properties of mutants of G. sulfurreducens strain DL1 analyzed using cyclic voltammetry. Here we report our most recent results advancing this modeling and its application investigate the cause of enhanced power generation by G. sulfurreducens strain KN400 analyzed by cyclic voltammetry and impedance spectroscopy.
