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

An Inner Membrane Cytochrome Required Only for Reduction of High Redox Potential Extracellular Electron Acceptors

mBio, 2014
Dissimilatory metal-reducing bacteria, such as Geobacter sulfurreducens, transfer electrons beyond their outer membranes to Fe(III) and Mn(IV) oxides, heavy metals, and electrodes in electrochemical devices.

Anode potential influences the structure and function of anodic electrode and electrolyte-associated microbiomes [PDF]

, 2016
Three bioelectrochemical systems were operated with set anode potentials of +300 mV, +550 mV and +800 mV vs. Standard Hydrogen Electrode (SHE) to test the hypothesis that anode potential influences microbial diversity and is positively associated with ...

Physiological Stratification in Electricity‐Producing Biofilms of Geobacter sulfurreducens

ChemSusChem, 2013
AbstractThe elucidation of mechanisms and limitations in electrode respiration by electroactive biofilms is significant for the development of rapidly emerging clean energy production and wastewater treatment technologies. In Geobacter sulfurreducens biofilms, the controlling steps in current production are thought to be the metabolic activity of cells,

Expressing the Geobacter metallireducens PilA in Geobacter sulfurreducens Yields Pili with Exceptional Conductivity

mBio, 2017
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.

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 ...

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 ...

Application of electro-active biofilms [PDF]

, 2010
The concept of an electro-active biofilm (EAB) has recently emerged from a few studies that discovered that certain bacteria which form biofilms on conductive materials can achieve a direct electrochemical connection with the electrode surface using it ...
