Physiological function and catalytic versatility of bacterial multihaem cytochromescinvolved in nitrogen and sulfur cycling [PDF]

, 2011
Bacterial MCCs (multihaem cytochromes c) represent widespread respiratory electron-transfer proteins. In addition, some of them convert substrates such as nitrite, hydroxylamine, nitric oxide, hydrazine, sulfite, thiosulfate or hydrogen peroxide. In many

Defined Electrosynthetic Microbial Consortia Reveal Electron Transfer Modes Governing Acetate Production

Advanced Science, Volume 13, Issue 6, 30 January 2026.
Spatially resolved Shewanella–acetogen interactions link DIET and MET pathways to acetate formation, offering a generalizable framework for designing structured, high‐efficiency microbial electrosynthesis systems. Abstract Precise manipulation of interspecies electron transfer (IET) is critical for advancing microbial electrosynthesis (MES) toward ...

Anaerobic Benzene Oxidation via Phenol in Geobacter metallireducens [PDF]

Applied and Environmental Microbiology, 2013
ABSTRACTAnaerobic activation of benzene is expected to represent a novel biochemistry of environmental significance. Therefore, benzene metabolism was investigated inGeobacter metallireducens, the only genetically tractable organism known to anaerobically degrade benzene.

The Role of Fe(II) Minerals in Carbon Stabilization in Coastal and Estuarine Anoxic Environments

Global Biogeochemical Cycles, Volume 40, Issue 1, January 2026.
Abstract Fe(III) (oxyhydr)oxides are well‐known for their role in organic carbon (OC) stabilization in terrestrial soils. Coastal and estuarine soils typically act as iron sinks and receive a high input of OC. However, tidal submersion induces anoxic and reducing conditions that favor the microbial reductive dissolution of Fe(III) (oxyhydr)oxides ...

Determining incremental coulombic efficiency and physiological parameters of early stage Geobacter spp. enrichment biofilms.

PLoS ONE, 2020
Geobacter spp. enrichment biofilms were cultivated in batch using one-chamber and two-chamber bioelectrochemical reactors. Time-resolved substrate quantification was performed to derive physiological parameters as well as incremental coulombic efficiency

Geobacter sulfurreducens can protect 304L stainless steel against pitting in conditions of low electron acceptor concentrations [PDF]

, 2010
The effect of Geobacter sulfurreducens cells was studied on the electrochemical behaviour of 304L stainless steel, emphasizing the role of the soluble electron acceptor (fumarate). In fumarate-lacking media, the presence of G. sulfurreducens induced free

Millimetre‐Scale Stratification of Microbial Communities in Hydrothermal Sediments

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Zooming into the millimetre‐scale spatial distribution of organic molecules in hydrothermally impacted sediments using mass spectrometry imaging reveals a distinct lipid zonation with abrupt transitions at critical redox interfaces. This zonation reflects a pronounced stratification of diverse microbial communities and highlights surprisingly ...
