Methane-Dependent Extracellular Electron Transfer at the Bioanode by the Anaerobic Archaeal Methanotroph “Candidatus Methanoperedens”

Frontiers in Microbiology, 2022
Anaerobic methanotrophic (ANME) archaea have recently been reported to be capable of using insoluble extracellular electron acceptors via extracellular electron transfer (EET).

Optimizing Microbial Fuel Cell Efficiency Through a Designed Electrogenic Consortium to Remove Alkylbenzenes

ChemElectroChem, Volume 13, Issue 10, 19 May 2026.
A mangrove‐derived electrogenic microbial consortium was successfully acclimated to codegrade ethylbenzene and xylenes in a microbial fuel cell (MFC). Acclimation provided high degradation efficiencies (up to 97%) and improved energy recovery. The MFC reached voltage of 520 mV and power density of 63.4 mW m−2.

Diversity and Metabolic Potential of the Terrestrial Mud Volcano Microbial Community with a High Abundance of Archaea Mediating the Anaerobic Oxidation of Methane

Life, 2021
Terrestrial mud volcanoes (TMVs) are important natural sources of methane emission. The microorganisms inhabiting these environments remain largely unknown. We studied the phylogenetic composition and metabolic potential of the prokaryotic communities of

Impact of conductive magnetite nanoparticles and anode polarization on glucose fermentation

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 5, Page 1027-1034, May 2026.
Abstract BACKGROUND Electrically conductive materials and electrochemical stimulation strategies are increasingly explored to steer microbial fermentation towards desired metabolic outputs. These approaches also hold remarkable potential to couple wastewater treatment (WWT) to the production of value‐added compounds, in turn enhancing environmental ...

Linking NrfD/PsrC‐like architecture to energy conservation: Functional residues in the quinone reactive QrcABCD complex of sulfate‐reducing bacteria

Protein Science, Volume 35, Issue 5, May 2026.
Abstract The QrcABCD quinone reductase complex is an electrogenic complex present in sulfate‐reducing bacteria of the Desulfobacterota phylum. It operates as a cytochrome c3:menaquinone oxidoreductase involved in electron transfer from periplasmic hydrogen or formate oxidation to the menaquinone (MK) pool.

Ultrafast Light-Driven Electron Transfer in a Ru(II)tris(bipyridine)-Labeled Multiheme Cytochrome [PDF]

Journal of the American Chemical Society, 2019
Multiheme cytochromes attract much attention for their electron transport properties. These proteins conduct electrons across bacterial cell walls and along extracellular filaments and when purified can serve as bionanoelectronic junctions. Thus, it is important and necessary to identify and understand the factors governing electron transfer in this ...

Electroenzymatic Cascades for Nitrogen Upgrading: Beyond Ammonia Towards Value‐Added Nitrogen Chemicals

ChemCatChem, Volume 18, Issue 7, 14 April 2026.
This review maps how electroenzymatic cascades that couple nitrogen‐cycle enzymes with C─N bond forming auxilary enzymes, powered by direct electron transfer (DET) or mediated electron transfer (MET), can upgrade N2 and waste nitrogen streams into value‐added amines, amides, amino acids, and other nitrogen‐based chemicals.

MmcA is an electron conduit that facilitates both intracellular and extracellular electron transport in Methanosarcina acetivorans

Nature Communications
Methanogens are a diverse group of Archaea that obligately couple energy conservation to the production of methane. Some methanogens encode alternate pathways for energy conservation, like anaerobic respiration, but the biochemical details of this ...

Rieske Iron–Sulfur Cluster Proteins From an Anaerobic Ammonium Oxidizer Suggest Unusual Energetics in Their Parent Rieske/Cytochrome b Complexes

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 4, Page 905-920, April 2026.
ABSTRACT Anaerobic ammonium‐oxidizing (anammox) bacteria employ a unique, hydrazine‐based pathway to obtain energy from nitrite and ammonium. These organisms possess distinct Rieske/cytochrome b complexes whose precise role in anammox metabolism remains unclear, but which have been proposed to include the generation of NAD(P)H.

Distribution and activity of nitrate and nitrite reductases in the microbiota of the human intestinal tract

The FEBS Journal, Volume 293, Issue 6, Page 1624-1642, March 2026.
Nitrate from food is first converted to nitrite by oral bacteria and then further processed in the intestine. The gut microbiota reduces nitrate and nitrite to ammonia or nitric oxide, preventing the formation of carcinogenic nitrosamines. Our analysis highlights Escherichia coli as a key player in this detoxification process, supported by other ...
