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

Proc Natl Acad Sci U S A, 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 ...

Anaerobic oxidation of methane: an "active" microbial process. [PDF]

Microbiologyopen, 2015
AbstractThe anaerobic oxidation of methane (AOM) is an important sink of methane that plays a significant role in global warming. AOM was first found to be coupled with sulfate reduction and mediated by anaerobic methanotrophic archaea (ANME) and sulfate‐reducing bacteria (SRB).

Carbon monoxide metabolism in freshwater anaerobic methanotrophic archaea [PDF]

Nature Communications
Anaerobic methanotrophic archaea mitigate methane emissions in anoxic environments as key members of the biological methane filter. Despite their ecological significance, physiology of anaerobic methanotrophs remains poorly understood.

Metal-driven anaerobic oxidation of methane and the Sturtian deglaciation [PDF]

Nature Communications
The Sturtian and Marinoan glaciations shaped Neoproterozoic palaeoenvironmental evolution. While methane emission likely intensified the Marinoan greenhouse effect, its role during the Sturtian glaciation—coinciding with widespread iron formations (IFs ...

Active pathways of anaerobic methane oxidization in deep-sea cold seeps of the South China Sea

Microbiology Spectrum, 2023
Anaerobic oxidation of methane (AOM) is critical for controlling methane emissions from deep-sea cold seeps. Microbial groups associated with different AOM processes have been briefly investigated, but the AOM activities associated with the utilization ...

Anaerobic Oxidation of Methane and Ammonium [PDF]

Annual Review of Microbiology, 2004
▪ Abstract  Anaerobic oxidation of methane and ammonium are two different processes catalyzed by completely unrelated microorganisms. Still, the two processes do have many interesting aspects in common. First, both of them were once deemed biochemically impossible and nonexistent in nature, but have now been identified as major factors in global ...

Anaerobic oxidation of methane in grassland soils used for cattle husbandry [PDF]

Biogeosciences, 2012
While the importance of anaerobic methane oxidation has been reported for marine ecosystems, the role of this process in soils is still questionable.

Methanotrophs: Discoveries, Environmental Relevance, and a Perspective on Current and Future Applications

Frontiers in Microbiology, 2021
Methane is the final product of the anaerobic decomposition of organic matter. The conversion of organic matter to methane (methanogenesis) as a mechanism for energy conservation is exclusively attributed to the archaeal domain.

Model-based investigation of membrane biofilm reactors coupling anammox with nitrite/nitrate-dependent anaerobic methane oxidation

Environment International, 2020
An innovative process coupling anaerobic ammonium oxidation (anammox) with nitrite/nitrate-dependent anaerobic methane oxidation (n-DAMO) in membrane biofilm reactors (MBfRs) has been developed to achieve high-level nitrogen removal from both sidestream (

Assessing the Effect of Humic Substances and Fe(III) as Potential Electron Acceptors for Anaerobic Methane Oxidation in a Marine Anoxic System

Microorganisms, 2020
Marine anaerobic methane oxidation (AOM) is generally assumed to be coupled to sulfate reduction, via a consortium of anaerobic methane-oxidizing archaea (ANME) and sulfate-reducing bacteria (SRB).
