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

Recent advances in electron transfer between biofilms and metals [PDF]

, 2007
Microbial biofilms produce electrochemical interactions with metal surfaces by following a wide variety of different electron exchange pathways. Reviewing the mechanisms identified in the biocorrosion of steels leads us to distinguish direct and indirect

The genome of Pelobacter carbinolicus reveals surprising metabolic capabilities and physiological features [PDF]

, 2012
Background The bacterium Pelobacter carbinolicus is able to grow by fermentation, syntrophic hydrogen/formate transfer, or electron transfer to sulfur from short-chain alcohols, hydrogen or formate; it does not oxidize acetate and is not known to ferment

Charge accumulation and electron transfer kinetics in Geobacter sulfurreducens biofilms

Energy & Environmental Science, 2012
Electroactive bacteria can use a polarized electrode as final electron acceptor, allowing the use of electrochemical techniques for a very accurate quantification of its respiration rate. Biofilm cell respiration has been recently demonstrated to continue after the interruption of electrode polarization since these bacteria can store electrons in the ...

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 ...
