Hydrothermal activity lowers trophic diversity in Antarctic sedimented hydrothermal vents [PDF]
, 2016 Sedimented hydrothermal vents are those in which hydrothermal fluid vents through sediment and are among the least studied deep-sea ecosystems. We present a combination of microbial and biochemical data to assess trophodynamics between and within ...

Frontiers in Environmental Science, 2022 Eutrophication is expected to increase methane production in freshwater sediments worldwide over the coming decades. Methane-oxidizing bacteria (MOB) consume a significant fraction of this sedimentary methane, but the factors that control their ...

A scalable model for methane consumption in arctic mineral soils
Geophysical Research Letters, 2016 Recent field studies have documented a surprisingly strong and consistent methane sink in arctic mineral soils, thought to be due to high‐affinity methanotrophy.

Methanotrophy below pH 1 by a new Verrucomicrobia species [PDF]
Nature, 2007 Mud volcanoes, mudpots and fumaroles are remarkable geological features characterized by the emission of gas, water and/or semi-liquid mud matrices with significant methane fluxes to the atmosphere (10(-1) to 10(3) t y(-1)). Environmental conditions in these areas vary from ambient temperature and neutral pH to high temperatures and low pH.

Frontiers in Microbiology, 2015 Aerobic methane-oxidizing bacteria are a diverse group of microorganisms that are ubiquitous in natural environments. Along with anaerobic methane-oxidizing bacteria and archaea, aerobic methanotrophs are critical for attenuating emission of methane to ...

Novel Methanotrophs of the Family Methylococcaceae from Different Geographical Regions and Habitats [PDF]
, 2015 Terrestrial methane seeps and rice paddy fields are important ecosystems in the methane cycle. Methanotrophic bacteria in these ecosystems play a key role in reducing methane emission into the atmosphere.

Quantification of methane oxidation in the rice rhizosphere using 13C-labelled methane [PDF]
, 2003 In this paper isotope ratio mass spectrometry is used to determine the methane (CH4) oxidation fraction in the rhizosphere of intact rice plant-soil systems.

Insights into the Ecological Roles and Evolution of Methyl-Coenzyme M Reductase-Containing Hot Spring Archaea [PDF]
, 2019 Several recent studies have shown the presence of genes for the key enzyme associated with archaeal methane/alkane metabolism, methyl-coenzyme M reductase (Mcr), in metagenome-assembled genomes (MAGs) divergent to existing archaeal lineages.

Methanotrophy induces nitrogen fixation during peatland development [PDF]
Proceedings of the National Academy of Sciences, 2013 SignificanceIn peatlands, the external sources of nitrogen are mainly atmospheric, but the atmospheric nitrogen deposition alone cannot explain the long-term annual nitrogen accumulation rates to these ecosystems. Because of methodological problems, methane-induced fixation of atmospheric dinitrogen gas has been previously overlooked as an additional ...

Microbial Ecology of Methanotrophy in Streams Along a Gradient of CH4 Availability [PDF]
Frontiers in Microbiology, 2020 Despite the recognition of streams and rivers as sources of methane (CH4) to the atmosphere, the role of CH4 oxidation (MOX) in these ecosystems remains poorly understood to date. Here, we measured the kinetics of MOX in stream sediments of 14 sites to resolve the ecophysiology of CH4 oxidizing bacteria (MOB) communities.
