The discovery of microorganisms with the ability of Extracellular Electron Transfer (EET), nearly three decades ago (Arnold et al. 1988, Lovley and Phillips 1988, Myers and Nealson 1988), sparked interest due to their ability to be used in diverse applications that can range from bioremediation to electricity production in Microbial Fuel Cells (MFC) (Erable et al. 2010).
