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

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).

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

Proceedings of the National Academy of Sciences of the United States of America, 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 ...

Contrasting Pathways for Anaerobic Methane Oxidation in Gulf of Mexico Cold Seep Sediments [PDF]

mSystems, 2019
Gulf of Mexico sediments harbor numerous hydrocarbon seeps associated with high sedimentation rates and thermal maturation of organic matter. These ecosystems host abundant and diverse microbial communities that directly or indirectly metabolize ...

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.

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 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.

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 (

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.

The effects of organic matter and anaerobic oxidation of methane on the microbial sulfate reduction in cold seeps

Frontiers in Marine Science, 2023
Cold seep sediments are dominated by intensive microbial sulfate reduction coupled to anaerobic oxidation of methane. However, the contribution proportion between this process and the role of organic matter has remained enigmatic.
