Biological Iron‐Monosulfide Production for Efficient Electricity Harvesting from a Deep‐Sea Metal‐Reducing Bacterium

FeS source: A metal-reducing bacterium, Shewanella loihica PV-4, has evolved the ability to utilize Fe 3d electrons from biogenic FeS as a long-distance electron-transfer conduit. Self-organizing, electron-conducting cellular networks enable the generation of a microbial current two orders of magnitude higher than in cell cultures lacking the biogenic minerals.
