Geochemistry, faunal composition and trophic structure in reducing sediments on the southwest South Georgia margin [PDF]

open access: yes, 2016
Despite a number of studies in areas of focused methane seepage, the extent of transitional sediments of more diffuse methane seepage, and their influence upon biological communities is poorly understood.

Aerobic and Anaerobic Methanotrophic Communities Associated with Methane Hydrates Exposed on the Seafloor: A High-Pressure Sampling and Stable Isotope-Incubation Experiment

open access: yesFrontiers in Microbiology, 2017
High-pressure (HP) environments represent the largest volumetric majority of habitable space for microorganisms on the planet, including the deep-sea and subsurface biosphere.

Genomic insights into methanotrophy: the complete genome sequence of Methylococcus capsulatus (Bath).

open access: yesPLoS Biology, 2004
Methanotrophs are ubiquitous bacteria that can use the greenhouse gas methane as a sole carbon and energy source for growth, thus playing major roles in global carbon cycles, and in particular, substantially reducing emissions of biologically generated ...

Phototrophic Methane Oxidation in a Member of the Chloroflexi Phylum [PDF]

open access: yes, 2019
Biological methane cycling plays an important role in Earth's climate and the global carbon cycle, with biological methane oxidation (methanotrophy) modulating methane release from numerous environments including soils, sediments, and water columns ...

A genomic timescale of prokaryote evolution: insights into the origin of methanogenesis, phototrophy, and the colonization of land

open access: yesBMC Evolutionary Biology, 2004
Background The timescale of prokaryote evolution has been difficult to reconstruct because of a limited fossil record and complexities associated with molecular clocks and deep divergences.

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

open access: yesBiogeosciences, 2009
Low affinity methanotrophic bacteria consume a significant quantity of methane in wetland soils in the vicinity of plant roots and at the oxic-anoxic interface.

Methane stimulates massive nitrogen loss from freshwater reservoirs in India

open access: yesNature Communications, 2018
The fate of anthropogenic nitrogen (N) remains understudied in South Asian water bodies despite its impact on water chemistry and quality. Here the authors show that N loss in Indian freshwater reservoirs is tightly coupled to methanotrophy, which has ...

Greenhouse Gas Emissions Over a Tidal Cycle in a Freshwater Wetland [PDF]

open access: yes, 2016
Tidal freshwater wetlands are located at the interface of non-tidal freshwater riverine systems and estuarine tidal systems. These habitats experience freshwater tides, creating unique redoximorphic soil characteristics while simultaneously presenting an

Identifying thermogenic and microbial methane in deep water Gulf of Mexico Reservoirs [PDF]

open access: yes, 2020
The Gulf of Mexico (GOM) produces 5% of total U.S. dry gas production (USEIA, 2016). Despite this, the proportion of microbial and thermogenic methane in discovered and producing fields from this area is still not well understood.
