Scientific Reports, 2022 Direct interspecies electron transfer (DIET) has been identified as an efficient metabolism between symbiotically interacting organisms. One method of DIET uses conductive materials (e.g., granular activated carbon (GAC)) as a medium to shuttle electrons

Role of direct microbial electron transfer in corrosion of steels [PDF]
, 2009 It has recently been discovered that many microbial species have the capacity to connect their metabolism to solid electrodes, directly exchanging electrons with them through membrane-bound redox compounds,nevertheless such a direct electron transfer ...

Heat-shock sigma factor RpoH from Geobacter sulfurreducens [PDF]
Microbiology, 2007 Recent studies with Myxococcus xanthus have suggested that homologues of the Escherichia coli heat-shock sigma factor, RpoH, may not be involved in the heat-shock response in this delta-proteobacterium. The genome of another delta-proteobacterium, Geobacter sulfurreducens, which is considered to be a representative of the Fe(III)-reducing ...

Mechanisms of Bacterial Extracellular Electron Exchange. [PDF]
, 2016 The biochemical mechanisms by which microbes interact with extracellular soluble metal ions and insoluble redox-active minerals have been the focus of intense research over the last three decades. The process presents two challenges to the microorganism;

Geabacter species enhances pit depth on 304L stainless steel in a medium lacking with electron donor [PDF]
, 2009 Geobacter sulfurreducens bacteria increased the open circuit potential of 304L stainless steel by around 320 mV in only a few hours after inoculation. This represents a significant increase in the corrosion risk.

Biochemical Capacitance of Geobacter Sulfurreducens Biofilms
ChemSusChem, 2015 AbstractAn electrical model able to decouple the electron pathway from microbial cell machinery impedance terms is introduced. In this context, capacitance characteristics of the biofilm are clearly resolved. In other words, the model allows separating, according to the advantage of frequency and spectroscopic response approach, the different terms ...

Enhanced Uranium Immobilization and Reduction by Geobacter sulfurreducens Biofilms [PDF]
Applied and Environmental Microbiology, 2014 ABSTRACT Biofilms formed by dissimilatory metal reducers are of interest to develop permeable biobarriers for the immobilization of soluble contaminants such as uranium. Here we show that biofilms of the model uranium-reducing bacterium Geobacter sulfurreducens immobilized substantially more U(VI) than ...
