Molecular mechanisms regulating the catabolic and electrochemical activities of <i>Shewanella oneidensis</i> MR-1

ABSTRACT Electrochemically active bacteria (EAB) interact electrochemically with electrodes via extracellular electron transfer (EET) pathways. These have attracted significant attention due to their utility in environmental-friendly bioelectrochemical systems (BESs), including microbial fuel cells and electrofermentation systems. The electrochemical activity of EAB is dependent on carbon catabolism respiration; thus, understanding how these processes are regulated will provide insights into the development a more efficient BES. process biofilm formation by BES also important for electric current generation because it facilitates physical interactions between electrodes. This article summarizes knowledge EET-related metabolic cellular functions model EAB, Shewanella oneidensis MR-1, focusing specifically regulatory catabolism, EET pathways, formation. Based recent developments, author discusses potential uses engineered S. strains various biotechnological applications.
