Abstract
Cytochrome proteins on the outer surface of Shewanella oneidensis bacteria interact directly with iron oxides in minerals to produce electrical currents, according to Thomas A. Clarke and David J. Richardson of the University of East Anglia in Norwich, United Kingdom, and their collaborators there and at the Pacific Northwest National Laboratory in Richland, Washington. Details appear in the April 16, 2013 Proceedings of the National Academy of Sciences (doi: 10.1073/pnas.1220074110).
