Archaea catalyze iron-dependent anaerobic oxidation of methane [PDF]

, 2016
Anaerobic oxidation of methane (AOM) is crucial for controlling the emission of this potent greenhouse gas to the atmosphere. Nitrite-, nitrate-, and sulfate-dependent methane oxidation is well-documented, but AOM coupled to the reduction of oxidized ...

Microbial colonization of basaltic glasses in hydrothermal organic-rich sediments at Guaymas Basin. [PDF]

, 2013
International audienceOceanic basalts host diverse microbial communities with various metabolisms involved in C, N, S, and Fe biogeochemical cycles which may contribute to mineral and glass alteration processes at, and below the seafloor.

Consumption of Methane and CO_2 by Methanotrophic Microbial Mats from Gas Seeps of the Anoxic Black Sea [PDF]

, 2007
The deep anoxic shelf of the northwestern Black Sea has numerous gas seeps, which are populated by methanotrophic microbial mats in and above the seafloor.

Environmental control on anaerobic oxidation of methane in gassy sediments of Eckernförde Bay (German Baltic) [PDF]

, 2005
We investigated the effect of seasonal environmental changes on the rate and distribution of anaerobic oxidation of methane (AOM) in Eckernforde Bay sediments (German Baltic Sea) and identified organisms that are likely to be involved in the process ...

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.

Novel Extended Tetraether Lipids Found in a High‐CO2 Geyser

Environmental Microbiology, Volume 28, Issue 3, March 2026.
Characterisation of the archaeal lipidome of the CO2‐rich subsurface aquifer of the Geyser Andernach reveals novel extended tetraether lipids analogous to extended archaeols, likely produced by Candidatus Altiarchaeum, and potentially functioning as a membrane adaptation strategy to nutrient‐deprived conditions.

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).

The Mechanism of Sodium Sulfate Coupled with Anaerobic Methane Oxidation Mitigating Methane Production in Beef Cattle

Microorganisms
The aim of this experiment is to explore the effect of sodium sulfate (Na2SO4) on methane reduction in the rumen, and its impact on anaerobic methane-oxidizing archaea (ANME).

Methane seep in shallow-water permeable sediment harbors high diversity of anaerobic methanotrophic communities, Elba, Italy

Frontiers in Microbiology, 2016
The anaerobic oxidation of methane (AOM) is a key biogeochemical process regulating methane emission from marine sediments into the hydrosphere. AOM is largely mediated by consortia of anaerobic methanotrophic archaea (ANME) and sulfate-reducing bacteria

Microbial communities of deep-sea methane seeps at Hikurangi continental margin (New Zealand). [PDF]

PLoS ONE, 2013
The methane-emitting cold seeps of Hikurangi margin (New Zealand) are among the few deep-sea chemosynthetic ecosystems of the Southern Hemisphere known to date. Here we compared the biogeochemistry and microbial communities of a variety of Hikurangi cold
