Trace-gas metabolic versatility of the facultative methanotroph Methylocella silvestris [PDF]

open access: yes, 2014
The climate-active gas methane is generated both by biological processes and by thermogenic decomposition of fossil organic material, which forms methane and short-chain alkanes, principally ethane, propane and butane1, 2. In addition to natural sources,

Large methane oxidation across an oxygen gradient in Baltic Sea deep waters

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Robust estimations of methane (CH4) oxidation in marginal seas remain elusive, making CH4 budgets particularly uncertain. Here, we investigate the CH4 benthic source and bottom layer oxidation across the entire Baltic Sea using concentration and stable isotope (δ13C‐CH4) profiles along oxygen and salinity gradients.

Drastic suppression of benthic nitrogen fixation by restructuring diazotrophic communities following tidal wetland conversion to aquaculture ponds

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Tidal wetland reclamation is a widespread anthropogenic disturbance that alters sediment biogeochemistry; however, its impacts on biological nitrogen fixation (BNF) and diazotrophic communities remain poorly understood. Here, we integrated 15N isotope labeling, metagenomic sequencing, and network analysis across a bare tidal flat (B), moderate‐

Diversity of active root-associated methanotrophs of three emergent plants in a eutrophic wetland in northern China

open access: yesAMB Express, 2020
Root-associated aerobic methanotrophs play an important role in regulating methane emissions from the wetlands. However, the influences of the plant genotype on root-associated methanotrophic structures, especially on active flora, remain poorly ...

Diversity and potential activity of methanotrophs in high methane-emitting permafrost thaw ponds. [PDF]

open access: yesPLoS ONE, 2017
Lakes and ponds derived from thawing permafrost are strong emitters of carbon dioxide and methane to the atmosphere, but little is known about the methane oxidation processes in these waters.

Effects of long‐term flood irrigation and fertilization on greenhouse gas emissions and soil nitrogen in mountain hay meadows

open access: yesSoil Science Society of America Journal, Volume 90, Issue 1, January/February 2026.
Abstract Mountain hay meadows are a high‐elevation forage‐producing agroecosystem dependent on flood irrigation and nitrogen (N) fertilization to maintain yields, meaning management has great potential to influence greenhouse gas (GHG) emissions. To assess GHG fluxes and inorganic N dynamics in meadows, field monitoring was established at four ranches ...

Ammonium Impacts Methane Oxidation and Methanotrophic Community in Freshwater Sediment

open access: yesFrontiers in Bioengineering and Biotechnology, 2020
Lacustrine ecosystems are regarded as one of the important natural sources of greenhouse gas methane. Aerobic methane oxidation, carried out by methane-oxidizing bacteria, is a key process regulating methane emission.

Understanding methanotroph ecology in a biofilter for efficiently mitigating methane emissions : a thesis presented in fulfilment of the requirements for the degree of Doctor of Philosophy in Soil Science (Biotechnology) at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2016
In New Zealand, the majority of the greenhouse gas (GHG), methane (CH4) emissions are from the agriculture sector (enteric fermentation, manure management) and the remainder from solid waste disposal, coal mining and natural gas leaks.

Activity of type I methanotrophs dominates under high methane concentration: methanotrophic activity in slurry surface crusts as influenced by methane, oxygen, and inorganic nitrogen [PDF]

open access: yes, 2017
Livestock slurry is a major source of atmospheric methane (CH4), but surface crusts harboring methane-oxidizing bacteria (MOB) could mediate against CH4 emissions.

Land Cover and Hydrology Regulate Riverine Carbon Emissions From Subarctic Catchments

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Streams transport carbon (C) and nutrients across the terrestrial‐aquatic interface and are significant sources of methane (CH4) and carbon dioxide (CO2) to the atmosphere. Climate‐induced changes in vegetation and hydrology increase the export of dissolved organic carbon (DOC) from terrestrial to aquatic ecosystems, but the impact of these ...
