Asymmetric coordination activated lattice oxygen in perovskite ferrites for selective anaerobic oxidation of methane

Journal of Materials Chemistry A, 2023
Tuning lattice oxygen in iron-based oxides that efficiently activates methane while prevents over-oxidation reaction remains challenging. This paper demonstrates the discovery of constructing asymmetric Fe-O-Al motif in perovskite ferrites to...

Assessing the effect of sulfate on the anaerobic oxidation of methane coupled with Cr(VI) bioreduction by sludge characteristic and metagenomics analysis.

Journal of Environmental Management, 2023
Methane-driven hexavalent chromium (Cr(VI)) reduction in a microbial fuel cell (MFC) has attracted much attention. However, whether the presence of sulfate (SO42-) affects the reduction of Cr(VI) is still lacking in systematic studies.

Simultaneous nitrate and sulfate dependent anaerobic oxidation of methane linking carbon, nitrogen and sulfur cycles.

Water Research, 2021
ANaerobic MEthanotrophic (ANME) archaea are critical microorganisms mitigating methane emission from anoxic zones. In previous studies, sulfate-dependent anaerobic oxidation of methane (AOM) and nitrate-dependent AOM, performed by different clades of ...

Roles and opportunities for microbial anaerobic oxidation of methane in natural and engineered systems

Energy & Environmental Science, 2021
Anaerobic oxidation of methane (AOM) is a crucial bioprocess in global methane mitigation. Adoption of AOM in an engineered system provides an opportunity for the development of methane-based biotechnologies.

Soil nitrogen substances and denitrifying communities regulate the anaerobic oxidation of methane in wetlands of Yellow River Delta, China.

Science of the Total Environment, 2022
Anaerobic oxidation of methane (AOM) in wetland soils is widely recognized as a key sink for the greenhouse gas methane (CH4). The occurrence of this reaction is influenced by several factors, but the exact process and related mechanism of this reaction ...

First evidence for anaerobic oxidation of methane process in landfill cover soils: Activity and responsible microorganisms.

Science of the Total Environment, 2022
Landfill cover soils (LCS) play important roles in mitigating methane emissions from landfills. Anaerobic oxidation of methane (AOM) has been demonstrated as a potential methane removal process in aquatic ecosystems.

The synergy of Fe(III) and NO2- drives the anaerobic oxidation of methane.

Science of the Total Environment, 2022
The anaerobic oxidation of methane (AOM) driven by NO2- or Fe(III) alone was limited by slow electron delivery and ineffective enrichment of microbes. The flexible coupling between Fe(III) and NO2- potentially cooperated to accelerate AOM.

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.
