Comparative bioelectricity production from various wastewaters in microbial fuel cells using mixed cultures and a pure strain of Shewanella oneidensis

► Shewanella oneidensis MR-1for the treatment of four different wastewaters in a microbial fuel cell. ► Comparative studies with wastewater endogenous microbes and wastewater endogenous microbes with MR-1. ► Maximum substrate removal in MFC was likely due to biomass growth. ► Electrochemical activity was pertinent to the MR-1 redox compound.
