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 ...

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 ...
