Community‐Level Analysis: Key Genes of Aerobic Methane Oxidation

2005
Aerobic methane-oxidizing bacteria (methanotrophs) are a diverse group of bacteria that are currently represented by 13 recognized genera. They play a major role in the global methane cycle and are widespread in nature with representatives found in soils, freshwater, seawater, freshwater and marine sediments, peat bogs and at extremes of temperature ...

Nitrogen removal by co-occurring methane oxidation, denitrification, aerobic ammonium oxidation, and anammox

Applied Microbiology and Biotechnology, 2009
The pathway for removing NO(3)(-) and NH(4)(+) from wastewater in the presence of both CH(4) and O(2) was clarified by studying microbial activity and community. Batch incubation tests were performed to characterize the microbial activity of the sludge, which was acclimatized in a bioreactor in which O(2) and CH(4) were supplied to treat wastewater ...

Is the role of aerobic methanotrophs underestimated in methane oxidation under hypoxic conditions?

Science of the Total Environment, 2022
Microbial methane oxidation is the major biological methane (CH4) sink in the carbon cycle. Methanotrophs can use various electron acceptors in addition to oxygen; understanding the role and contribution of methanotrophs is thus an important topic ...

Methylobacter accounts for strong aerobic methane oxidation in the Yellow River Delta with characteristics of a methane sink during the dry season.

Science of the Total Environment, 2019
Recent investigations demonstrate that some coastal wetlands are atmospheric methane sinks, but the regulatory mechanisms are not clear. Here, the main pathway and operator of methane oxidation in the Yellow River Delta (YRD) wetland, a methane source in

Potential for Aerobic Methane Oxidation in Carboniferous Coal Measures

Geomicrobiology Journal, 2014
Carbon (C), geologically sequestered in coal, is gradually released to the atmosphere as CH4 and CO2. Recent anthropogenic activity (coal mining) has rapidly increased the rate of C reallocation from coal deposits into the atmosphere, which has deleterious effect on the climate as both gases are effective infrared absorbers.

Effect of salt stress on aerobic methane oxidation and associated methanotrophs; a microcosm study of a natural community from a non-saline environment

Soil Biology and Biochemistry, 2018
We investigated the response of aerobic methane oxidation and the associated methanotrophs to salt-stress in a NaCl gradient ranging from 0 M (un-amended reference) to 0.6 M NaCl (seawater salinity) using a rice paddy soil as a model system.

Anaerobic oxidation of methane by aerobic methanotrophs in sub-Arctic lake sediments

Science of The Total Environment, 2017
Anaerobic oxidation of methane (AOM) is a biological process that plays an important role in reducing the CH4 emissions from a wide range of ecosystems. Arctic and sub-Arctic lakes are recognized as significant contributors to global methane (CH4) emission, since CH4 production is increasing as permafrost thaws and provides fuels for methanogenesis ...

[Engineering application of aerobic methane oxidizing bacteria (methanotrophs): a review].

Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2022
Aerobic methane oxidizing bacteria (methanotrophs) can use methane as carbon source and energy source, eliminating 10%-20% of global methane. Methanotrophs can also effectively synthesize valuable methane-derived products. This article introduced the methane oxidizing mechanism of methanotrophs, and summarized the practical application and research ...

Methane-oxidizing archaea, aerobic methanotrophs and nitrifiers coexist with methane as the sole carbon source

International Biodeterioration & Biodegradation, 2019
Abstract Methane oxidation plays a key role in carbon and nutrient cycling and has the potential to be applied in engineered bioprocesses, including wastewater and gas treatments. To provide insights into the dynamics of the methanotrophic community under microoxic and anoxic conditions, two sequencing batch reactors under microoxic (MO2-SBR) and ...
