Microbial Reduction of Antimony(V)-Bearing Ferrihydrite by Geobacter sulfurreducens. [PDF]
Applied and Environmental Microbiology, 2023 The reduction of Sb(V)-bearing ferrihydrite by Geobacter sulfurreducens was studied to determine the fate of the metalloid in Fe-rich systems undergoing redox transformations. Sb(V) added at a range of concentrations adsorbed readily to ferrihydrite, and

Relationship of electrochemical performance and biofilm development of Desulfuromonas acetexigens and Geobacter sulfurreducens in microbial electrolysis cells [PDF]
Frontiers in MicrobiologyDesulfuromonas acetexigens has gained attention as a biocatalyst in microbial electrolysis cells (MECs) due to its inability to utilize hydrogen as an electron donor, which favors beneficial Coulombic efficiencies (CE). In this study, the electrochemical

The Restorative Effects of Electron Mediators on the Formation of Electroactive Biofilms in Geobacter sulfurreducens [PDF]
MicroorganismsElectroactive biofilms (EABs) are essential for the performance of bioelectrochemical systems (BESs), but their formation in Geobacter, critically on conductive pili and exopolysaccharides, limits application under conditions where these components are ...

Syntrophic Growth of Geobacter sulfurreducens Accelerates Anaerobic Denitrification [PDF]
Frontiers in Microbiology, 2018 Nitrate is considered as a contamination since it’s over discharging to water incurs environmental problems. However, nitrate is an ideal electron sink for anaerobic pollutant degraders desiring electron acceptors due to the high redox potential ...

Recent Origin of the Methacrylate Redox System in Geobacter sulfurreducens AM-1 through Horizontal Gene Transfer. [PDF]
PLoS ONE, 2015 The origin and evolution of novel biochemical functions remains one of the key questions in molecular evolution. We study recently emerged methacrylate reductase function that is thought to have emerged in the last century and reported in Geobacter ...

Comparative transcriptomics of closely related Geobacter sulfurreducens strains uncovers strain-level variations in extracellular electron transfer [PDF]
Frontiers in MicrobiologyMembers of Geobacter sulfurreducens are electroactive bacteria that transfer electrons to extracellular solid electron acceptors using extracellular electron transport (EET) pathways, thereby generating currents in bioelectrochemical systems (BESs ...

Quantification of microaerobic growth of Geobacter sulfurreducens. [PDF]
PLoS ONE, 2020 Geobacter sulfurreducens was originally considered a strict anaerobe. However, this bacterium was later shown to not only tolerate exposure to oxygen but also to use it as terminal electron acceptor.

Formation of nanoscale elemental silver particles via enzymatic reduction by Geobacter sulfurreducens [PDF]
, 2008 Geobacter sulfurreducens reduced Ag(I) (as insoluble AgCl or Ag+ ions), via a mechanism involving c-type cytochromes, precipitating extracellular nanoscale Ag(0). These results extend the range of metals known to be reduced by Geobacter species and offer
