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 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 ...

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

Methane release from sediment seeps to the atmosphere is counteracted by highly active Methylococcaceae in the water column of deep oligotrophic Lake Constance. [PDF]
FEMS Microbiology Ecology, 2016 Methane emissions from freshwater environments contribute substantially to global warming but are under strong control of aerobic methane-oxidizing bacteria. Recently discovered methane seeps (pockmarks) in freshwater lake sediments have the potential to bypass this control by their strong outgassing activity.

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 ...

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.

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 ...

Metagenomic identification of active methanogens and methanotrophs in serpentinite springs of the Voltri Massif, Italy [PDF]
PeerJ, 2017 The production of hydrogen and methane by geochemical reactions associated with the serpentinization of ultramafic rocks can potentially support subsurface microbial ecosystems independent of the photosynthetic biosphere.

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

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 ...
