Genetically Boosting Electron Transfer in Electroactive Biofilms for Improved Sensitivity of Microbial Fuel Cell‐Based Biosensing

Microbial Biotechnology, Volume 19, Issue 4, April 2026.
Engineering Geobacter biofilms through the manipulation of the cyclic GMP‐AMP signalling system led to the formation of thin, highly conductive bioanodes. This boosted extracellular electron transfer, enabling a microbial fuel cell biosensor with a 20‐fold lower Cd(II) detection limit (0.03 mg L−1) by increasing cytochromes/nanowires and reducing ...

Interspecies Electron Transfer via Hydrogen and Formate Rather than Direct Electrical Connections in Cocultures of Pelobacter carbinolicus and Geobacter sulfurreducens

, 2012
Direct interspecies electron transfer (DIET) is an alternative to interspecies H-2/formate transfer as a mechanism for microbial species to cooperatively exchange electrons during syntrophic metabolism.

Lactate Oxidation Coupled to Iron or Electrode Reduction by Geobacter sulfurreducens PCA

, 2011
Geobacter sulfurreducens PCA completely oxidized lactate and reduced iron or an electrode, producing pyruvate and acetate intermediates. Compared to the current produced by Shewanella oneidensis MR-1, G.

Anode biofilm transcriptomics reveals outer surface components essential for high density current production in Geobacter sulfurreducens fuel cells.

PLoS ONE, 2009
The mechanisms by which Geobacter sulfurreducens transfers electrons through relatively thick (>50 microm) biofilms to electrodes acting as a sole electron acceptor were investigated. Biofilms of Geobacter sulfurreducens were grown either in flow-through

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

, 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.

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 ...
