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

Enhancing methane production from food waste fermentate using biochar. The added value of electrochemical testing in pre-selecting the most effective type of biochar [PDF]

, 2017
Background: Recent studies have suggested that addition of electrically conductive biochar particles is an effective strategy to improve the methanogenic conversion of waste organic substrates, by promoting syntrophic associations between acetogenic and ...

Different outer membrane c‐type cytochromes are involved in direct interspecies electron transfer to Geobacter or Methanosarcina species

mLife, 2022
Direct interspecies electron transfer (DIET) may be most important in methanogenic environments, but mechanistic studies of DIET to date have primarily focused on cocultures in which fumarate was the terminal electron acceptor.

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 ...

Deep-4mCGP: A Deep Learning Approach to Predict 4mC Sites in Geobacter pickeringii by Using Correlation-Based Feature Selection Technique

International Journal of Molecular Sciences, 2022
4mC is a type of DNA alteration that has the ability to synchronize multiple biological movements, for example, DNA replication, gene expressions, and transcriptional regulations.

Electrochemical Characterization of the Periplasmic PpcA c‐Cytochrome of Geobacter sulfurreducens Reveals Its Affinity for Uranium

ChemElectroChem, 2023
Geobacter bacteria produce conductive pili appendages and an outer membrane‐anchored lipopolysaccharide to immobilize uranium extracellularly. Yet, some radionuclide enters the cell envelope, where is rapidly mineralized by periplasmic c‐cytochromes.

Geobacter, Anaeromyxobacter and Anaerolineae populations are enriched on anodes of root exudate-driven microbial fuel cells in rice field soil [PDF]

, 2015
Plant-based sediment microbial fuel cells (PMFCs) couple the oxidation of root exudates in living rice plants to current production. We analysed the composition of the microbial community on anodes from PMFC with natural rice field soil as substratum for

Geobacter bremensis sp. nov. and Geobacter pelophilus sp. nov., two dissimilatory ferric-iron-reducing bacteria. [PDF]

International Journal of Systematic and Evolutionary Microbiology, 2001
Two strictly anaerobic, dissimilatory ferric-iron-reducing bacteria, strains Dfr1T and Dfr2T, were isolated from freshwater mud samples with ferrihydrite as electron acceptor. Both strains also grew by reducing Mn(IV), S0 and fumarate. Electron donors used by strains Dfr1T and Dfr2T for growth with ferric iron as electron acceptor included hydrogen ...

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;

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.
