Common Diarrhea-Causing Bacterium Found to Produce Electricity

Researchers at the University of California (UC), Berkeley, say they have discovered that a common diarrhea-causing bacterium, Listeria monocytogenes , produces electricity using an entirely different method from known electrogenic bacteria, and that hundreds of other bacterial species use this same process. Their study (“ A flavin-based extracellular electron transfer mechanism in diverse Gram-positive bacteria ”), published online in Nature , will be good news for those currently t
