Thermophilic methane oxidation is widespread in Aotearoa-New Zealand geothermal fields

Frontiers in Microbiology, 2023
Geothermal areas represent substantial point sources for greenhouse gas emissions such as methane. While it is known that methanotrophic microorganisms act as a biofilter, decreasing the efflux of methane in most soils to the atmosphere, the diversity ...

Thermophilic methanotrophs: in hot pursuit

FEMS Microbiology Ecology, 2019
ABSTRACTMethane is a potent greenhouse gas responsible for 20–30% of global climate change effects. The global methane budget is ∼500–600 Tg y−1, with the majority of methane produced via microbial processes, including anthropogenic-mediated sources such as ruminant animals, rice fields, sewage treatment facilities and landfills.

Environmental Preferences and Functional Variations of Methanotrophs in Northeast Qinghai‐Tibet Plateau Wetlands

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Significant environmental preference between type I and type II methanotrophs is regulated by soil ion concentration (pH and electrical conductivity) in wetlands. Type II methanotrophs (Methylocystis, etc.) contributes more to soil methane oxidation than type I methanotrophs.

Biotic interactions in microbial communities as modulators of biogeochemical processes: Methanotrophy as a model system.

Frontiers in Microbiology, 2016
Microbial interaction is an integral component of microbial ecology studies, yet the role, extent, and relevance of microbial interaction in community functioning remains unclear, particularly in the context of global biogeochemical cycles.

Ammonium addition inhibits 13C-methane incorporation into methanotroph membrane lipids in a freshwater sediment

, 1999
To investigate the effect of ammonium addition on the species composition and activity of freshwater methane oxidizing bacteria, intact sediment cores were labeled with (CH4)-C-13 and incubated under ambient and elevated ammonium concentrations.

Foliar Contributions to Methane and Nitrous Oxide Exchange in Urban Green Roof Systems

GCB Bioenergy, Volume 18, Issue 6, June 2026.
Biochar amendment of extensive green roof substrates enhanced foliar methane (CH4) uptake (~3×) and reduced nitrous oxide (N2O) emissions across native and stonecrop vegetation. City‐scale extrapolation to Toronto's permitted green roof area indicates measurable, management‐sensitive non‐CO2 mitigation within urban green infrastructure systems ...

Methanotrophic activity and diversity of methanotrophs in volcanic geothermal soils at Pantelleria (Italy) [PDF]

Biogeosciences, 2014
Abstract. Volcanic and geothermal systems emit endogenous gases by widespread degassing from soils, including CH4, a greenhouse gas twenty-five times as potent as CO2. Recently, it has been demonstrated that volcanic or geothermal soils are not only a source of methane, but are also sites of methanotrophic activity. Methanotrophs are able to consume 10–

Denitrification performance, kinetics, and microbial community of methanol‐driven heterotrophic denitrification processes for treating nitrate‐rich water in recirculating mariculture system

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Large‐scale application of methanol‐driven heterotrophic denitrification (MHD) biofilms to recirculating mariculture systems (RMSs) is constrained by the requirement of precise methanol dosage. The emergence of intelligent aquaculture offers an opportunity to address this challenge, necessitating a comprehensive understanding of the ...

Activity and abundance of methane-oxidizing bacteria in secondary forest and manioc plantations of Amazonian Dark Earth and their adjacent soils

Frontiers in Microbiology, 2014
The oxidation of atmospheric CH4 in upland soils is mostly mediated by uncultivated groups of microorganisms that have been identified solely by molecular markers, such as the sequence of the pmoA gene encoding the β-subunit of the particulate methane ...

Termite mounds contain soil-derived methanotroph communities kinetically adapted to elevated methane concentrations [PDF]

, 2020
Termite mounds have recently been confirmed to mitigate approximately half of termite methane (CH4) emissions, but the aerobic CH4 oxidising bacteria (methanotrophs) responsible for this consumption have not been resolved. Here, we describe the abundance,
