Biofilm Biology and Engineering of Geobacter and Shewanella spp. for Energy Applications
Frontiers in Bioengineering and Biotechnology, 2021 Geobacter and Shewanella spp. were discovered in late 1980s as dissimilatory metal-reducing microorganisms that can transfer electrons from cytoplasmic respiratory oxidation reactions to external metal-containing minerals.

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 ...

Two Modes of Riboflavin-Mediated Extracellular Electron Transfer in Geobacter uraniireducens
Frontiers in Microbiology, 2018 Anaerobes respire extracellular electron acceptors by extracellular electron transfer (EET). It is widely recognized that flavins can act as electron shuttles to facilitate this process. Flavin synthesis genes are widely distributed in Geobacter species.

Syntrophic Growth of Geobacter sulfurreducens Accelerates Anaerobic Denitrification
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 ...

Integrative analysis of Geobacter spp. and sulfate-reducing bacteria during uranium bioremediation [PDF]
Biogeosciences, 2012 Enhancing microbial U(VI) reduction with the addition of organic electron donors is a promising strategy for immobilizing uranium in contaminated groundwaters, but has yet to be optimized because of a poor understanding of the factors controlling the ...
