Electroactive Microbiomes: Electron Transfer Mechanisms and Environmental Biotechnology Applications

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Electroactive microbiomes couple direct, mediated, conductive, and interspecies electron transfer with biofilm organisation to drive wastewater treatment, bioremediation, resource recovery, carbon conversion, and biosensing. Their performance depends on balancing electron transfer, mass transport, community structure, and electrode–biofilm interactions

Energy Conservation via Hydrogen Cycling in the Methanogenic Archaeon Methanosarcina barkeri

open access: yesmBio, 2018
Energy conservation via hydrogen cycling, which generates proton motive force by intracellular H2 production coupled to extracellular consumption, has been controversial since it was first proposed in 1981.

Resonance Raman analysis of intracellular vitamin B12 analogs in methanogenic archaea

open access: yesAnalytical Science Advances, 2022
Methanogenic archaea (methanogens) are microorganisms that can synthesize methane. They are found in diverse environments ranging from paddy fields to animal digestive tracts to deep‐sea hydrothermal vents.

Liquid Metals as Dynamic and Programmable Catalysts for Photocatalysis

open access: yesChemCatChem, Volume 18, Issue 18, 28 September 2026.
Adaptive liquid metals enable dynamic metal–semiconductor interfaces that boost light absorption and charge separation. Serving as electronic and plasmonic platforms, they drive advanced photocatalysis. This review outlines key mechanisms, design strategies, and applications for solar fuels and environmental cleanup.

Cometabolism of ferrihydrite reduction and methyl-dismutating methanogenesis by Methanosarcina mazei

open access: yesApplied and Environmental Microbiology
Recent discoveries have shown that some Methanosarcina species can reduce Fe(III), reshaping our understanding of Methanosarcina ecophysiology. However, the specific minerals reduced, the products formed, and the underlying metabolic mechanisms remain ...

Structure and haem-distal site plasticity in Methanosarcina acetivorans protoglobin. [PDF]

open access: yesPLoS ONE, 2013
Protoglobin from Methanosarcina acetivorans C2A (MaPgb), a strictly anaerobic methanogenic Archaea, is a dimeric haem-protein whose biological role is still unknown.

Prokaryotic Novelty and Metabolic Diversity in the Tagoro Shallow Hydrothermal System (Canary Islands, Spain)

open access: yesEnvironmental Microbiology, Volume 28, Issue 9, September 2026.
Hydrothermal activity at the Tagoro submarine volcano shapes distinct epipelagic and benthic prokaryotic communities. Microbial diversity decreases towards vent sources, yet novel taxa dominate and potentially contribute to iron, nitrogen, sulphur and methane cycling in this shallow hydrothermal system with high unexplored microbial diversity ...

Hydrothermal Contributions to Elevated Dissolved Organic Carbon Concentrations and Cycling Along the Mid‐Atlantic Ridge

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Hydrothermal systems along the Mid‐Atlantic Ridge (MAR) are spatially variable sources of dissolved organic carbon (DOC) to the deep ocean, with implications for carbon cycling and trace‐metal transport. We present DOC measurements from four research cruises focusing on major vent fields at Menez Gwen, Rainbow, Lost City, Broken Spur and TAG ...
