Summary:[...]if a synthetic electrode is poised at a favorable redox potential, it is possible to "trick" the metal-reducing bacteria into transferring their electrons to the electrode surface in the absence of any other electron acceptor. [...]while most gram-negative bacteria and mitochondria confine these electrontransfer reactions to the inner membrane of the cell or organelle, Shewanella and Geobacter locate some of their heme-containing cytochromes on the outer membrane, where the molecules can access external, solid electron acceptors, such as a mineral surface.
