Comparative genomics of Geobacter chemotaxis genes reveals diverse signaling function [PDF]

BMC Genomics, 2008
Background Geobacter species are δ-Proteobacteria and are often the predominant species in a variety of sedimentary environments where Fe(III) reduction is important. Their ability to remediate contaminated environments and produce electricity makes them

The genome of Geobacter bemidjiensis, exemplar for the subsurface clade of Geobacter species that predominate in Fe(III)-reducing subsurface environments.

BMC Genomics, 2010
Background Geobacter species in a phylogenetic cluster known as subsurface clade 1 are often the predominant microorganisms in subsurface environments in which Fe(III) reduction is the primary electron-accepting process.

Effect of model methanogens on the electrochemical activity, stability, and microbial community structure of Geobacter spp. dominated biofilm anodes [PDF]

npj Biofilms and Microbiomes
Combining anaerobic digestion (AD) and microbial electrochemical technologies (MET) in AD-MET holds great potential. Methanogens have been identified as one cause of decreased electrochemical activity and deterioration of Geobacter spp. biofilm anodes. A

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

Synthesis of Palladium Nanoparticles by Electrode-Respiring Geobacter sulfurreducens Biofilms [PDF]

, 2023
The electroactive microorganism Geobacter sulfurreducens can couple organic electron donor oxidation to the respiration of electrode surfaces, colonizing them in the process.

Effect of Geobacter sulfurreducens on the microbial corrosion of mild steel, ferritic and austenitic stainless steels [PDF]

, 2009
The influence of Geobacter sulfurreducens was tested on the anaerobic corrosion of four different steels: mild steel 1145, ferritic steel 403 and austenitic steels 304L and 316L.

Effect of surface roughness, biofilm coverage and biofilm structure on the electrochemical efficiency of microbial cathodes [PDF]

, 2011
Biofilms of Geobacter sulfurreducens were formed under chronoamperometry at −0.5 V and −0.6 V vs. Ag/AgCl on stainless steel cathodes and tested for fumarate reduction.

Development of a whole-cell biosensor based on an ArsR-Pars regulatory circuit from Geobacter sulfurreducens

Environmental Science and Ecotechnology, 2021
In this study, an Escherichia coli (E. coli) whole-cell biosensor for the specific detection of bioavailable arsenic was developed by placing a green fluorescent protein (GFP) reporter gene under the control of the ArsR1 (GSU2952) regulatory circuit from

Microbial Communities and Electrochemical Performance of Titanium-Based Anodic Electrodes in a Microbial Fuel Cell [PDF]

, 2011
Four types of titanium (Ti)-based electrodes were tested in the same microbial fuel cell (MFC) anodic compartment. Their electrochemical performances and the dominant microbial communities of the electrode biofilms were compared.

Conductive Particles Enable Syntrophic Acetate Oxidation between Geobacter and Methanosarcina from Coastal Sediments

mBio, 2018
Coastal sediments are rich in conductive particles, possibly affecting microbial processes for which acetate is a central intermediate. In the methanogenic zone, acetate is consumed by methanogens and/or syntrophic acetate-oxidizing (SAO) consortia.
