Frontiers in Microbiology, 2012 Methane is the second most abundant greenhouse gas in the atmosphere. A major part of the total methane emissions from lake ecosystems are emitted from littoral wetlands. Methane emissions are significantly reduced by methanotrophs as they use methane as

Novel Methanotrophs of the Family Methylococcaceae from Different Geographical Regions and Habitats [PDF]
, 2015 Terrestrial methane seeps and rice paddy fields are important ecosystems in the methane cycle. Methanotrophic bacteria in these ecosystems play a key role in reducing methane emission into the atmosphere.

Comparative Analysis of Root Microbiomes of Rice Cultivars with High and Low Methane Emissions Reveals Differences in Abundance of Methanogenic Archaea and Putative Upstream Fermenters. [PDF]
, 2020 Rice cultivation worldwide accounts for ∼7 to 17% of global methane emissions. Methane cycling in rice paddies is a microbial process not only involving methane producers (methanogens) and methane metabolizers (methanotrophs) but also other microbial ...

Planktonic and sediment-associated aerobic methanotrophs in two seep systems along the North American margin [PDF]
, 2008 Methane vents are of significant geochemical and ecological importance. Notable progress has been made towards understanding anaerobic methane oxidation in marine sediments, however, the diversity and distribution of aerobic methanotrophs in the water ...

Simultaneous sulfide and methane oxidation by an extremophile
Nature Communications, 2023 Hydrogen sulfide (H2S) and methane (CH4) are produced in anoxic environments through sulfate reduction and organic matter decomposition. Both gases diffuse upwards into oxic zones where aerobic methanotrophs mitigate CH4 emissions by oxidizing this ...

A four-helix bundle stores copper for methane oxidation [PDF]
, 2015 Methane-oxidising bacteria (methanotrophs) require large quantities of copper for the membrane-bound (particulate) methane monooxygenase (pMMO). Certain methanotrophs are also able to switch to using the iron-containing soluble MMO (sMMO) to catalyse ...

The role of methanotrophy in the microbial carbon metabolism of temperate lakes
Nature Communications, 2022 Methane metabolism is considered of secondary importance in most lake food webs. Here the authors quantify the contribution of methanotrophs to C cycling in six lakes, finding evidence of a large role of methanotrophs due to their higher specific ...

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.

Niche differentiation in nitrogen metabolism among methanotrophs within an operational taxonomic unit [PDF]
, 2014 Background: The currently accepted thesis on nitrogenous fertilizer additions on methane oxidation activity assumes niche partitioning among methanotrophic species, with activity responses to changes in nitrogen content being dependent on the in situ ...

Macroecology of methane-oxidizing bacteria: the β-diversity of pmoA genotypes in tropical and subtropical rice paddies [PDF]
, 2013 Studies addressing microbial biogeography have increased during the past decade, but research on microbial distribution patterns is still in its infancies, and many aspects are only poorly understood. Here, we compared the methanotroph community in paddy
