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

Limnology 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.

Active Methanotrophs in Suboxic Alpine Swamp Soils of the Qinghai–Tibetan Plateau

Frontiers in Microbiology, 2020
Methanotrophs are the only biofilters for reducing the flux of global methane (CH4) emissions in water-logged wetlands. However, adaptation of aerobic methanotrophs to low concentrations of oxygen and nitrogen in typical swamps, such as that of the ...

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

Limnology 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‐

Genomic Reconstruction of an Uncultured Hydrothermal Vent Gammaproteobacterial Methanotroph (Family Methylothermaceae) Indicates Multiple Adaptations to Oxygen Limitation [PDF]

, 2015
Hydrothermal vents are an important contributor to marine biogeochemistry, producing large volumes of reduced fluids, gasses, and metals and housing unique, productive microbial and animal communities fueled by chemosynthesis.

Winter cover crops alter methanotrophs community structure in a double-rice paddy soil

Journal of Integrative Agriculture, 2016
Methanotrophs play a vital role in the mitigation of methane emission from soils. However, the influences of cover crops incorporation on paddy soil methanotrophic community structure have not been fully understood.

Role of methanotrophic communities in atmospheric methane oxidation in paddy soils

Frontiers in Microbiology
Wetland systems are known methane (CH4) sources. However, flooded rice fields are periodically drained. The paddy soils can absorb atmospheric CH4 during the dry seasons due to high-affinity methane-oxidizing bacteria (methanotroph).

Abundance, rather than composition, of methane‐cycling microbes mainly affects methane emissions from different vegetation soils in the Zoige alpine wetland

MicrobiologyOpen, 2019
Methane fluxes, which are controlled by methanogens and methanotrophs, vary among wetland vegetation species. In this study, we investigated belowground methanogens and methanotrophs in two soils under two different dominant vegetation species with ...

Ökologie methanotropher Bakterien: Räumliche Verteilung und Funktion methanotropher Bakterien in Feuchtgebieten.

, 2010
Methan ist neben CO2 das wichtigste Treibhausgas, dessen relatives Treibhauspotential ungefähr ein drittel höher liegt als das von CO2. Der Großteil atmosphärischen Methans wird dabei aus biogenen Methanquellen freigesetzt, zum Beispiel renaturierte Mülldeponien, Feuchtgebiete oder Reisfelder.

Methylotetracoccus oryzae Strain C50C1 Is a Novel Type Ib Gammaproteobacterial Methanotroph Adapted to Freshwater Environments

mSphere, 2019
Methane-oxidizing microorganisms perform an important role in reducing emissions of the greenhouse gas methane to the atmosphere. To date, known bacterial methanotrophs belong to the Proteobacteria, Verrucomicrobia, and NC10 phyla.
