Isolation and characterization of electrochemically active bacteria from an anaerobic digester treating food wastes

Studies have used anaerobic-digester sludge as inoculum for bioelectrochemical systems, such as microbial fuel cells, while limited studies have identified electrochemically active bacteria thriving in anaerobic digesters. In the present work, single-chamber MFCs were operated using anaerobic-digester effluents as the sole source of organics and microbes, and attempts were made to isolate EAB from anode biofilms.
