High current density via direct electron transfer by the halophilic anode respiring bacterium Geoalkalibacter subterraneus.
In this study the characterization of Geoalkalibacter subterraneus is presented, which is a novel halophilic anode respiring bacterium (ARB) previously selected and identified in a potentiostatically controlled bioelectrochemical system (BES) inoculated with sediments from a salt plant. Pure culture electroactive biofilms of Glk. subterraneus were grown during chronoamperometric batch experimen...
متن کاملInfluence of Anode Potentials on Current Generation and Extracellular Electron Transfer Paths of Geobacter Species
Geobacter species are capable of utilizing solid-state compounds, including anodic electrodes, as electron acceptors of respiration via extracellular electron transfer (EET) and have attracted considerable attention for their crucial role as biocatalysts of bioelectrochemical systems (BES's). Recent studies disclosed that anode potentials affect power output and anodic microbial communities, in...
متن کاملMtr extracellular electron-transfer pathways in Fe(III)-reducing or Fe(II)-oxidizing bacteria: a genomic perspective.
Originally discovered in the dissimilatory metal-reducing bacterium Shewanella oneidensis MR-1 (MR-1), key components of the Mtr (i.e. metal-reducing) pathway exist in all strains of metal-reducing Shewanella characterized. The protein components identified to date for the Mtr pathway of MR-1 include four multihaem c-Cyts (c-type cytochromes), CymA, MtrA, MtrC and OmcA, and a porin-like outer m...
متن کاملFlavin Electron Shuttles Dominate Extracellular Electron Transfer by Shewanella oneidensis
UNLABELLED Shewanella oneidensis strain MR-1 is widely studied for its ability to respire a diverse array of soluble and insoluble electron acceptors. The ability to breathe insoluble substrates is defined as extracellular electron transfer and can occur via direct contact or by electron shuttling in S. oneidensis. To determine the contribution of flavin electron shuttles in extracellular elect...
متن کاملNitrate is a preferred electron acceptor for growth of freshwater selenate-respiring bacteria.
An anaerobic, freshwater enrichment grew with either nitrate or selenate as an electron acceptor. With both ions present, nitrate reduction preceded selenate reduction. An isolate from the enrichment grew on either ion, but the presence of nitrate precluded the reduction of selenate. Stock cultures of denitrifiers grew anaerobically on nitrate but not on selenate.
