The Role of Crystalline Iron Oxides in Methane Mitigation through Anaerobic Oxidation of Methane

ACS ES&T Water, 2021
Biological Fe(III)-dependent anaerobic oxidation of methane (AOM) is predicted to be a key methane sink in natural and anthropogenic environments. Crystalline Fe(III) is an important environmentally relevant form of Fe(III) in those environments, including aquifers, estuaries, marine sediments, and soils. However, its role in methane mitigation remains

Anaerobic Methane Oxidizers

2018
The anaerobic oxidation of methane (AOM) with sulfate as the final electron acceptor according to (CH4 + SO4 2− → HCO3 − + HS− + H2O) is the major sink of methane in the oceans and hence a significant process in the global carbon cycle and methane budget.

Metal Oxide Reduction Linked to Anaerobic Methane Oxidation

Trends in Microbiology, 2017
Microbial methanotrophy is important in mitigating methane emissions to the atmosphere. Geochemical evidence suggests the occurrence of anaerobic methane oxidation with metal oxides in natural environments. A study has now identified, for the first time, novel freshwater archaea of the order Methanosarcinales that can oxidize methane with Fe(III) and ...

Combined anaerobic ammonium and methane oxidation for nitrogen and methane removal

Biochemical Society Transactions, 2011
Anammox (anaerobic ammonium oxidation) is an environment-friendly and cost-efficient nitrogen-removal process currently applied to high-ammonium-loaded wastewaters such as anaerobic digester effluents. In these wastewaters, dissolved methane is also present and should be removed to prevent greenhouse gas emissions into the environment.

Anaerobic Methane Oxidizers

2010
Anaerobic methanotrophic archaea of the ANME clades -1, -2, -3 are cosmopolitan and ubiquitous in all environments on Earth where sulfate and methane intersect. Closely related gene sequences of anaerobic methanotrophs are found in subsurface and surface sediments, terrestrial, and marine settings or benthic and pelagic habitats.

Methyl sulfides as intermediates in the anaerobic oxidation of methane

Environmental Microbiology, 2007
Summary While it is clear that microbial consortia containing Archaea and sulfate‐reducing bacteria (SRB) can mediate the anaerobic oxidation of methane (AOM), the interplay between these microorganisms remains unknown.

Wastewater Opportunities for Denitrifying Anaerobic Methane Oxidation

Trends in Biotechnology, 2017
Denitrifying anaerobic methane oxidation (DAMO) can concurrently reduce methane emissions and nitrogen levels in aquatic environments, but how useful is this process? We propose the use of DAMO-based technology as a tool for sustainably operating wastewater treatment plants (WWTPs).

On the Problem of Anaerobic Methane Oxidation

Microbiology, 2004
To clarify the biological mechanism of anaerobic methane oxidation, experiments were performed with samples of the Black Sea anaerobic sediments and with the aerobic methane-oxidizing bacterium Methylomonas methanica strain 12. The inhibition–stimulation analysis did not allow an unambiguous conclusion to be made about a direct and independent role of ...

Methane clumped isotope signature of anaerobic oxidation of methane

2022
<p>Microbial anaerobic oxidation of methane (AOM) significantly mitigates atmospheric methane emissions on Earth and represents a thermodynamically favorable metabolic strategy for astrobiological targets where methane has been detected. The bulk carbon and hydrogen isotope ratios produced by AOM have been used to probe the thermodynamic ...

Enrichment of denitrifying anaerobic methane oxidizing microorganisms

Environmental Microbiology Reports, 2009
Summary The microorganisms responsible for anaerobic oxidation of methane (AOM) coupled to denitrification have not been clearly elucidated. Three recent publications suggested it can be achieved by a denitrifying bacterium with or without the involvement of anaerobic methanotrophic archaea.
