Methylococcaceae are the dominant active aerobic methanotrophs in a Chinese tidal marsh
Environmental Science and Pollution Research, 2018 Although coastal marshes are net carbon sinks, they are net methane sources. Aerobic methanotrophs in coastal marsh soils are important methane consumers, but their activity and populations are poorly characterized. DNA stable-isotope probing followed by sequencing was used to determine how active methanotrophic populations differed in the main ...

Communal metabolism by Methylococcaceae and Methylophilaceae is driving rapid aerobic methane oxidation in sediments of a shallow seep near Elba, Italy [PDF]
Environmental Microbiology, 2019 Summary The release of abiotic methane from marine seeps into the atmosphere is a major source of this potent greenhouse gas. Methanotrophic microorganisms in methane seeps use methane as carbon and energy source, thus significantly mitigating global methane emissions.

The Phylogenetic Position of the Family Methylococcaceae [PDF]
International Journal of Systematic Bacteriology, 1995 The 16S ribosomal DNA-based phylogenetic positions of various members of the Methylococcaceae (group I methanotrophs) were investigated. The Methylococcaceae as a whole formed a distinct branch in the gamma subdivision of the Proteobacteria, and this branch had five distinct subbranches. On the basis of a number of phenotypic traits, phospholipid fatty

Oxygen availability is a major factor in determining the composition of microbial communities involved in methane oxidation [PDF]
PeerJ, 2015 We have previously observed that methane supplied to lake sediment microbial communities as a substrate not only causes a response by bona fide methanotrophic bacteria, but also by non-methane-oxidizing bacteria, especially by members of the family ...

The methanol dehydrogenase gene, mxaF, as a functional and phylogenetic marker for proteobacterial methanotrophs in natural environments. [PDF]
PLoS ONE, 2013 The mxaF gene, coding for the large (α) subunit of methanol dehydrogenase, is highly conserved among distantly related methylotrophic species in the Alpha-, Beta- and Gammaproteobacteria.

A Novel Moderately Thermophilic Type Ib Methanotroph Isolated from an Alkaline Thermal Spring in the Ethiopian Rift Valley [PDF]
Microorganisms, 2020 Aerobic moderately thermophilic and thermophilic methane-oxidizing bacteria make a substantial contribution in the control of global warming through biological reduction of methane emissions and have a unique capability of utilizing methane as their sole

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.

Methane cycling microorganisms drive seasonal variation of methane emission in mangrove ecosystems [PDF]
Environmental MicrobiomeCoastal mangroves are one of the significant hotspots of natural methane (CH4) emissions, yet the seasonal dynamics of these emissions and the underlying microbial drivers remain poorly understood.

Revised Taxonomy of the Methanotrophs: Description of Methylobacter gen. nov., Emendation of Methylococcus, Validation of Methylosinus and Methylocystis Species, and a Proposal that the Family Methylococcaceae Includes Only the Group I Methanotrophs [PDF]
International Journal of Systematic Bacteriology, 1993 Numerical taxonomic, DNA-DNA hybridization, and phospholipid fatty acid composition analyses were performed on an extensive range of methanotrophic strains, including reference strains and environmental isolates obtained from sites throughout eastern Australia.
