Establishment and metabolic analysis of a model microbial community for understanding trophic and electron accepting interactions of subsurface anaerobic environments

BMC Microbiology, 2010
Background Communities of microorganisms control the rates of key biogeochemical cycles, and are important for biotechnology, bioremediation, and industrial microbiological processes.

Proteome of Geobacter sulfurreducens in the presence of U(VI)

Microbiology, 2014
Geobacter species often play an important role in the in situ bioremediation of uranium-contaminated groundwater, but little is known about how these microbes avoid uranium toxicity. To evaluate this further, the proteome of Geobacter sulfurreducens exposed to 100 µM U(VI) acetate was compared to control cells not exposed to U(VI ...

Genomic Analyses of Bacterial Porin-Cytochrome Gene Clusters

Frontiers in Microbiology, 2014
The porin-cytochrome (Pcc) protein complex is responsible for trans-outer membrane electron transfer during extracellular reduction of Fe(III) by the dissimilatory metal-reducing bacterium Geobacter sulfurreducens PCA.

Distinct gating mechanisms revealed by the structures of a multi-ligand gated K+ channel

eLife, 2012
The gating ring-forming RCK domain regulates channel gating in response to various cellular chemical stimuli in eukaryotic Slo channel families and the majority of ligand-gated prokaryotic K+ channels and transporters.

Electronic transference assessment of the redox processes at carbon electrodes coated with Geobacter sulfurreducens that grown at different temperatures [PDF]

, 2011
In the present study, the kinetic parameters of redox reactions and the proteomic profiles of Geobacter sulfurreducens grown at different temperatures (25 ºC and 37 ºC) were evaluated. Oxidation peaks with different potentials and current intensities

Extracellular electron transfer proteins contribute to reduction of ferric minerals by Geobacter biofilms

Applied and Environmental Microbiology
To investigate how the thickness and extracellular electron transfer (EET) capabilities of microbial biofilms influence the reduction of ferric iron [Fe(III)]-containing minerals, we utilized four strains of Geobacter sulfurreducens with varying biofilm ...
