Distinct microbial communities drive methane cycling in below- and above-ground compartments of tropical cloud forests growing on peat [PDF]

Environmental Microbiome
Cloud forests are unique yet understudied ecosystems regarding CH4 exchange despite their significance in carbon storage. We investigated CH4 fluxes in peat soil and tree stems of two tropical cloud forests on Réunion Island, one featuring Erica ...

Metabolic flexibility of aerobic methanotrophs under anoxic conditions in Arctic lake sediments. [PDF]

ISME J, 2022
Abstract Methane (CH4) emissions from Arctic lakes are a large and growing source of greenhouse gas to the atmosphere with critical implications for global climate. Because Arctic lakes are ice covered for much of the year, understanding the metabolic flexibility of methanotrophs under anoxic conditions would aid in characterizing the ...

Impact of Copper on the Physiology and Transcriptome of Methylosinus Trichosporium OB3b Grown on Either Methane or Methanol. [PDF]

Environ Microbiol
Methylosinus trichosporium OB3b can grow on methanol in the absence but not presence of copper due: (1) overgeneration of reducing power from methanol oxidation; (2) formate accumulation leading to acidification of the growth medium and inactivation of formate dehydrogenase; and (3) lack of expression of potential oxidative stress defence genes ...

Leveraging genome-scale metabolic models to understand aerobic methanotrophs. [PDF]

ISME J
Abstract Genome-scale metabolic models (GEMs) are valuable tools serving systems biology and metabolic engineering. However, GEMs are still an underestimated tool in informing microbial ecology. Since their first application for aerobic gammaproteobacterial methane oxidizers less than a decade ago, GEMs have substantially increased our ...

Methanotrophs: Discoveries, Environmental Relevance, and a Perspective on Current and Future Applications

Frontiers in Microbiology, 2021
Methane is the final product of the anaerobic decomposition of organic matter. The conversion of organic matter to methane (methanogenesis) as a mechanism for energy conservation is exclusively attributed to the archaeal domain.

Aerobic methanotrophic bacteria of cold ecosystems [PDF]

FEMS Microbiology Ecology, 2005
This review summarizes the recent advances in understanding the ecophysiological role and structure-function features of methanotrophic bacteria living in various cold ecosystems. The occurrence of methanotrophs in a majority of psychrosphere sites was verified by direct measurement of their methane-utilizing activity, by electron microscopy and ...

No evidence of light inhibition on aerobic methanotrophs in coastal sediments using eDNA and eRNA

Environmental DNA, 2023
It is estimated that up to half of global methane (CH4) emissions are derived from microbial processes in aquatic ecosystems. However, it is not fully understood which factors explain the spatial and temporal variability of these emissions.

Diversity and Effect of Increasing Temperature on the Activity of Methanotrophs in Sediments of Fildes Peninsula Freshwater Lakes, King George Island, Antarctica

Frontiers in Microbiology, 2022
Global warming has a strong impact on polar regions. Particularly, the Antarctic Peninsula and nearby islands have experienced a marked warming trend in the past 50 years.

Identification of functionally active aerobic methanotrophs and their methane oxidation potential in sediments from the Shenhu Area, South China Sea

China Geology, 2022
: Large amounts of gas hydrate are distributed in the northern slope of the South China Sea, which is a potential threat of methane leakage. Aerobic methane oxidation by methanotrophs, significant methane biotransformation that occurs in sediment surface

Potential for Aerobic Methanotrophic Metabolism on Mars [PDF]

Astrobiology, 2019
Observational evidence supports the presence of methane (CH4) in the martian atmosphere on the order of parts per billion by volume (ppbv). Here, we assess whether aerobic methanotrophy is a potentially viable metabolism in the martian upper regolith, by calculating metabolic energy gain rates under assumed conditions of martian surface temperature ...
