Geobacter sulfurreducens biofilms developed under different growth conditions on glassy carbon electrodes: insights using cyclic voltammetry.
Growth of biofilms of G. sulfurreducens on glassy carbon that yield a bioelectrocatalytic response to acetate oxidation is achieved using a fixed applied potential, with current density for acetate oxidation scaling with applied potential. In contrast biofilms grown under electron acceptor-limiting conditions display redox signals shifted to lower potentials and do not oxidise acetate.
