Extracellular electron transfer (EET) in Geobacter sulfurreducens is mediated by outer-membrane cytochromes. We show that loss of outer-membrane cytochromes reduces G. sulfurreducens surface polarizability. In the contrast, G. sulfurreducens harvested from microbial fuel cell (MFC) anodes has enhanced surface polarizability compared to its original inoculum, and this increase is positively correlated with MFC incubation time and current production. These results suggest opportunities of using microfluidic dielectrophoresis (DEP) as a selection tool for electrochemically active organisms.
