Gut Bacteria’s Shocking Secret: They Produce Electricity

September 18, 2018

UC Berkeley scientists have discovered that a common diarrhea-causing bacterium, Listeria monocytogenes, produces electricity using an entirely different technique from known electrogenic bacteria—and that hundreds of other bacterial species use this same process. The scientists worked with Caroline Ajo-Franklin, a staff scientist at the Molecular Foundry who has a secondary appointment in Molecular Biophysics and Integrated Bioimaging, on this research.
