Abstract
Fe(II)-oxidizing bacteria play an important role in biogeochemical cycles. At circumneutral pH, these organisms perform extracellular electron transfer, taking up electrons from Fe(II) outside the cell, potentially through a porin-cytochrome complex in the outer membrane encoded by the Mto pathway.
