A long-term cultivation of an anaerobic methane-oxidizing microbial community from deep-sea methane-seep sediment using a continuous-flow bioreactor. [PDF]

PLoS ONE, 2014
Anaerobic oxidation of methane (AOM) in marine sediments is an important global methane sink, but the physiological characteristics of AOM-associated microorganisms remain poorly understood.

Geochemical and Microbial Signatures of Siboglinid Tubeworm Habitats at an Active Mud Volcano in the Canadian Beaufort Sea

Frontiers in Marine Science, 2021
During the ARA08C expedition in 2017, sediment push cores were collected at an active mud volcano (420 m water depth) in the Canadian Beaufort Sea from two visually discriminative siboglinid tubeworm (ST) habitats that were colonized densely and less ...

Microbial Communities Involved in Methane, Sulfur, and Nitrogen Cycling in the Sediments of the Barents Sea

Microorganisms, 2021
A combination of physicochemical and radiotracer analysis, high-throughput sequencing of the 16S rRNA, and particulate methane monooxygenase subunit A (pmoA) genes was used to link a microbial community profile with methane, sulfur, and nitrogen cycling ...

Methanogen activity and microbial diversity in Gulf of Cádiz mud volcano sediments

Frontiers in Microbiology, 2023
The Gulf of Cádiz is a tectonically active continental margin with over sixty mud volcanoes (MV) documented, some associated with active methane (CH4) seepage. However, the role of prokaryotes in influencing this CH4 release is largely unknown.

Metabolic capabilities of microorganisms involved in and associated with the anaerobic oxidation of methane

Frontiers in Microbiology, 2016
In marine sediments the anaerobic oxidation of methane with sulfate as electron acceptor (AOM) is responsible for the removal of a major part of the greenhouse gas methane.

The Impact of Methane on Microbial Communities at Marine Arctic Gas Hydrate Bearing Sediment

Frontiers in Microbiology, 2020
Cold seeps are characterized by high biomass, which is supported by the microbial oxidation of the available methane by capable microorganisms. The carbon is subsequently transferred to higher trophic levels.

Acetogenic Methane‐Carbon Monoxide Comproportionation: An Exergonic but Unobserved Microbial Metabolism

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Microbial metabolism relies on redox reactions that exploit chemical disequilibria. While aerobic carbon oxidation, carbon fixation, and fermentation are well studied, the broader space of anaerobic carbon redox reactions remains underexplored.

Kinetics of sulfate‐ and iron‐dependent anaerobic methane oxidation in freshwater lake sediment

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Anaerobic oxidation of methane (AOM) is a potentially important sink for methane in freshwater sediments. Assessing the contribution of AOM to methane budgets requires an understanding of AOM process kinetics, yet such information remains scarce.

Nitrogen and carbon flows in a microbial mat involving anaerobic oxidation of methane in northwestern Black Sea: perspectives from nitrogen and carbon isotopic composition of coenzyme F430 and its biosynthetic pathway

Progress in Earth and Planetary Science
Coenzyme F430, a nickel-containing tetrapyrrole, serves as a cofactor for methyl-coenzyme M reductase (MCR), which catalyzes both the final step of methanogenesis and the initial step of anaerobic oxidation of methane (AOM).
