is a model bacterial strain for studies of bioelectrochemical systems (BESs). It has two extracellular electron transfer pathways: (1) shuttling electrons an excreted mediator riboflavin; and (2) direct contact between the -type cytochromes at the cell membrane and the electrode. Despite the extensi...
