Methanotrophy potential versus methane supply by pore water diffusion in peatlands [PDF]

, 2008
International audienceLow affinity methanotrophic bacteria consume a significant quantity of methane in wetland soils in the vicinity of plant roots and at the oxic-anoxic interface.

Microbial and chemical predictors of methane release from a stratified thermokarst permafrost hotspot

Frontiers in Microbiology
Soils are dynamic interfaces that can act as both sources and sinks of methane (CH₄), yet the microbial processes underlying these fluxes remain poorly constrained in current Earth system models—particularly in thawing permafrost regions.

Methanotrophy in Movile Cave [PDF]

Movile Cave is an isolated cave ecosystem that receives no input of photosynthetically fixed carbon. Instead, carbon is primarily fixed through light- independent bacterial processes such as chemolithoautotrophy and methanotrophy. Distinctive microbial floating mats appear at the surface of groundwater flooding the cave, at the redox interface between ...

High diversity of methanotrophic bacteria in geothermal soils affected by high methane fluxes [PDF]

, 2014
Volcanic and geothermal systems emit endogenous gases by widespread degassing from soils, including CH4, a greenhouse gas 25 times as potent as CO2. Recently, it has been demonstrated that volcanic/geothermal soils act as source, but also as biological

Carbon Dioxide and Methane Emissions from a California Salt Marsh [PDF]

, 2017
Wetland carbon sequestration is offset by carbon dioxide (CO2) and methane (CH4) emissions for which the magnitudes remain coarsely constrained. To better understand the spatial and temporal variations of gaseous carbon fluxes from marsh soils in a ...

Constraints on mechanisms and rates of anaerobic oxidation of methane by microbial consortia: process-based modeling of ANME-2 archaea and sulfate reducing bacteria interactions [PDF]

, 2008
Anaerobic oxidation of methane (AOM) is the main process responsible for the removal of methane generated in Earth's marine subsurface environments. However, the biochemical mechanism of AOM remains elusive.
