	abstract = {<p>Extracellular electron transfer is a key metabolic process of many organismsthat enables them to exchange electrons with extracellular electrondonors/acceptors. The discovery of organisms with these abilities and theunderstanding of their electron transfer processes has become a priority for thescientific and industrial community, given the growing interest on the use ofthese organisms in sustainable biotechnological processes. For example, inbioelectrochemical systems electrochemical active organisms can exchangeelectrons with an electrode, allowing the production of energy and added-valuecompounds, among other processes. In these systems, electrochemical activeorganisms exchange electrons with an electrode through direct or indirectmechanisms, using, in most cases, multiheme cytochromes. In numerouselectroactive organisms, these proteins form a conductive pathway that allowselectrons produced from cellular metabolism to be transferred across the cellsurface for the reduction of an electrode, or vice-versa. Here, the mechanisms bywhich the most promising electroactive bacteria perform extracellular electrontransfer will be reviewed, emphasizing the proteins involved in these pathways.The ability of some of the organisms to perform bidirectional electron transferand the pathways used will also be highlighted.</p>
