Carboxydotrophic growth of Geobacter sulfurreducens [PDF]
Applied Microbiology and Biotechnology, 2015 This study shows that Geobacter sulfurreducens grows on carbon monoxide (CO) as electron donor with fumarate as electron acceptor. Geobacter sulfurreducens was tolerant to high CO levels, with up to 150 kPa in the headspace tested. During growth, hydrogen was detected in very slight amounts (∼5 Pa).

Anaerobic Benzene Oxidation by Geobacter Species [PDF]
Applied and Environmental Microbiology, 2012 ABSTRACTThe abundance ofGeobacterspecies in contaminated aquifers in which benzene is anaerobically degraded has led to the suggestion that someGeobacterspecies might be capable of anaerobic benzene degradation, but this has never been documented. A strain ofGeobacter, designated strain Ben, was isolated from sediments from the Fe(III)-reducing zone of

Biomineralization of Cu 2 S Nanoparticles by Geobacter sulfurreducens
Applied and Environmental Microbiology, 2020 Dissimilatory metal-reducing bacteria are ubiquitous in soils and aquifers and are known to utilize a wide range of metals as terminal electron acceptors. These transformations play an important role in the biogeochemical cycling of metals in pristine and contaminated environments and can be harnessed for bioremediation and metal ...

Expressing the Geobacter metallireducens PilA in Geobacter sulfurreducens Yields Pili with Exceptional Conductivity [PDF]
mBio, 2017 ABSTRACT The electrically conductive pili (e-pili) of Geobacter sulfurreducens serve as a model for a novel strategy for long-range extracellular electron transfer. e-pili are also a new class of bioelectronic materials.

Garden compost inoculum leads to microbial bioanodes with potential-independent characteristics [PDF]
, 2013 Garden compost leachate was used to form microbial bioanodes under polarization at 0.4, 0.2 and +0.1 V/SCE. Current densities were 6.3 and 8.9 A m2 on average at 0.4 and +0.1 V/SCE respectively, with acetate 10 mM.

Putative Extracellular Electron Transfer in Methanogenic Archaea
Frontiers in Microbiology, 2021 It has been suggested that a few methanogens are capable of extracellular electron transfers. For instance, Methanosarcina barkeri can directly capture electrons from the coexisting microbial cells of other species.
