Spatial Heterogeneity in Methane Biogeochemistry and Prokaryotic Community Structure in Sub-Arctic Waterbodies in Northern Canada. [PDF]
Environ MicrobiolProkaryotic communities and methane dynamics differed markedly across 16 sub‐Arctic waterbodies. Maximum depth and permafrost thaw emerged as key drivers, with non‐stratified thaw‐affected sites hosting distinct communities and elevated methane fluxes, highlighting their potential role as emerging hotspots of methane emissions.

Detection of methanotrophs with highly divergent pmoA genes from Arctic soils [PDF]
FEMS Microbiology Letters, 2002 Tundra soil samples from the Canadian Arctic community, Kuujjuaq, were analyzed for the presence of the soluble (sMMO) and particulate (pMMO) methane monooxygenase genes. Total genomic DNA extracted from these soils was used as template for PCR using sMMO- and pMMO-specific primers, mmoX1-mmoX2 and A189-A682, respectively.

Ammonium Impacts Methane Oxidation and Methanotrophic Community in Freshwater Sediment
Frontiers 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.

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 ...

Enrichment of denitrifying methane-oxidizing microorganisms using up-flow continuous reactors and batch cultures. [PDF]
PLoS ONE, 2014 Denitrifying anaerobic methane oxidizing (DAMO) microorganisms were enriched from paddy field soils using continuous-flow and batch cultures fed with nitrate or nitrite as a sole electron acceptor. After several months of cultivation, the continuous-flow
