Electron transfer capability and metabolic processes of the genus Shewanella with applications to the optimization of microbial fuel cells

UnrestrictedThe mechanisms that bacteria employ to transfer electrons to their surrounding environments are diverse and not well understood. This study provides original data that begin to elucidate specific mechanisms involved with electron transfer to microbial fuel cell (MFC) electrodes, Fe(III)- and Mn(IV)-oxides using various strains and species of the genus Shewanella. Additionally, MFC were used to study the carbon and energy metabolisms of several different Shewanella strains, identify efficiencies, and study the physiology of Shewanella oneidensis MR-1. These data have implications toward the optimization of bioremediation technologies, MFC development and to the fundamental understanding of how bacteria interact with and affect their environments
