When transferring electrons to insoluble Fe oxyhydroxide particles, the bacterium Geobacter sulfurreducens must utilize a chain of redox proteins to relay electrons from cytoplasmic electron carriers to external electron acceptors. In the presence of an electrode poised at an oxidizing potential, not only can cells in contact with the electrode respire directly to the surface, but 10 to 20 cell layers can stack upon each other, and each layer is also electrically connected to the electrode… CONTINUE READING
