Environmental Preferences and Functional Variations of Methanotrophs in Northeast Qinghai-Tibet Plateau Wetlands. [PDF]
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.

Rethinking Termite Methane Emissions: Does the Mound Environment Matter? [PDF]
Many factors can influence the amount of methane (CH4) that is released from a termite mound. In this study, we tested how the external and internal environment of a termite mound impacts CH4 emission using field measurements of mounds in a Northern Australia savanna.

Ammonium Impacts Methane Oxidation and Methanotrophic Community in Freshwater Sediment
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.

Upland soils of tundra function as a constant sink for atmospheric CH4 but the identity of methane oxidizers in these soils remains poorly understood. Methane uptake rates of −0.4 to −0.6 mg CH4-C m−2 day−1 were determined by the static chamber method in

Wide Distribution of a Novel pmoA -Like Gene Copy among Type II Methanotrophs, and Its Expression in Methylocystis Strain SC2 [PDF]
ABSTRACT Experiments were conducted to determine if a novel pmoA -like gene ( pmoA2 ) recently discovered in the methane-oxidizing bacterium Methylocystis strain SC2 (P. F. Dunfield, M. Tchawa Yimga, S. D. Dedysh, U. Berger, W. Liesack, and J.

Enrichment of denitrifying methane-oxidizing microorganisms using up-flow continuous reactors and batch cultures. [PDF]
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

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 ...

Introduction Farmlands are key sources of greenhouse gas (GHG) emissions, which are susceptible to changes in precipitation regimes. The soils of seasonal fallow contribute approximately half of annual GHG emissions from farmlands, but the effect of ...

Methane-cycling communities in a permafrost-affected soil on Herschel Island, Western Canadian Arctic: active layer profiling ofmcrAandpmoAgenes [PDF]
In Arctic wet tundra, microbial controls on organic matter decomposition are likely to be altered as a result of climatic disruption. Here, we present a study on the activity, diversity and vertical distribution of methane-cycling microbial communities in the active layer of wet polygonal tundra on Herschel Island.
