Diversity of methane and short chain hydrocarbon degrading bacteria with an emphasis on methane biofilter systems
Methanotrophs house enzymes capable of methane oxidation, act as a sink for atmospheric methane and play a key role in the global carbon cycle. This study conducted multiple studies on methanotrophs, including: examination of the evolutionary history of copper membrane monooxygenases (CuMMOs), …

A drinking water microbiome from source to tap: Community diversity, functionality, and microbial interaction
… to a variety of taxa. Both Type I and Type II methanotrophs dominated the finished water and distribution system. They mostly possessed methylotrophy pathways involving many enzymes rather than single enzyme systems. Network analysis determined potential species interaction between …

Role of microbial diversity in controlling greenhouse gas emissions from conserved forages
… the presence of functional genetic markers for methanotrophs and denitrifiers. The gene marker for methanotrophs (pmoA) was detected prior to the incubation and on the outside of the haybales post two months incubation but disappeared from the inside. The detection of methanogens on the inside …

An Isotopic Analysis of Carbon Dynamics in Sphagnum Peat
… supply available to Sphagnum from both symbiotic methanotrophs and heterotrophs. Mass balance calculations showed that Sphagnum associated methanotrophic communities only contribute a small proportion of the carbon fixed by Sphagnum growing in wet environments despite significant local oxidation. …

Metal contamination and methane oxidising bacteria around a formerly industrialised suburban rive
… of pollutants. One among such groups are methanotrophs, which grow on methane as their sole source of carbon and energy and are able to remediate diverse hydrophobic organic pollutants due to the wide range of substrates utilised by their oxygenase enzymes. Recently, it was shown that the …

Biological Conversion Process of Methane into Methanol Using Mixed Culture Methanotrophic Bacteria Enriched from Activated Sludge System
… methane bio-hydroxylation system using type I methanotrophs enriched from activated sludge system. The optimization resulted in a notable enhancement of the growth kinetics. The attained maximum specific growth rate (max) (0.358 hr-1) and maximum specific methane biodegradation rate (qmax) …

Organic geochemistry and stable isotope constraints on Precambrian biogeochemical processes
… of green and purple sulfur bacteria as well as methanotrophs and cyanobacteria. Possible environmental implications of these communities co-existing are explained in context of changes in ocean chemistry and the diversification of eukaryotic life.

Metal contamination and methane oxidising bacteria around a formerly industrialised suburban river.
… of pollutants. One among such groups are methanotrophs, which grow on methane as their sole source of carbon and energy and are able to remediate diverse hydrophobic organic pollutants due to the wide range of substrates utilised by their oxygenase enzymes. Recently, it was shown that the …

Organic geochemical biosignatures in alkaline Hydrothermal ecosystems
… other parts of the vent field at Lost City are methanotrophs. The application of lipid biomarkers helps unravel the multiple biological and abiotic sources of methane at Lost City.Closer examination of lipids from Lost City shows that most are ether-type glycolipids. The dominance of glycolipids …

Investigating the Distribution and Biosynthesis of Modified F<sub>430</sub> Cofactors in Methanogenic and Methanotrophic Archaea
… of methane (AOM) carried out by the anaerobic methanotrophs (ANME). Cofactor F<sub>430</sub>, a unique nickel-containing tetrapyrrole, serves as the prosthetic group and catalytic component of Mcr. Recently, multiple F<sub>430</sub> variants have been discovered in several methanogenic species, …

Microbial communities, activities, and metabolisms in Earth’s subseafloor and analog oceanic environments
… forearc, where mineral-associated microbial methanotrophs were detected, though microbial methanogenesis was not observed. The second part of the thesis focuses on cultivation-based approaches to characterize newly isolated microbes and their responses to high-pH and low-energy conditions. …

Methane Fluxes from Living and Dead Trees in a Temperate Forest
… Uptake is hypothesized to occur through methanotrophs within foliage, and emissions from channelling of methane that originates in soil. In an upland site tree branches, wounds, and stems emitted methane (averages = 0.61, 10.58, 0.59 nmol m-2 s-1; n = 18, 83, 79, respectively), and at the …

Recombinant Expression and Assembly of Methyl Coenzyme-M reductase
… archaea and its consumption by anaerobic methanotrophs (ANME). MCR is a multimeric complex composed of six different subunits arranged in a 2α, 2β, 2γ configuration that requires two molecules of its nickel-containing tetrapyrrole prosthetic group, coenzyme F430. Additionally, the α …

Characterizing methanogen and methanotroph diversity, abundance and activity within the Hampshire-Avon catchment
… found to likely be secondary factors affecting methanotrophs, with MOP only increasing with temperature if CH4 is abundant. N and P additions to soils had an overall negative effects on methanotrophy in clay soils but an overall positive effect in chalk soils, and no effect on greensand soils. …

The physiological characterisation of a novel Thermomicrobia strain WKT50.2, and a review of the characteristics of the class Thermomicrobia
… to the phyla Proteobacteria and Verrucomicrobia. Methanotrophs also tend to be metabolic specialists with no capability to oxidise substrates other than C1 compounds. In contrast, WKT50.2 was also able to oxidise ammonia and nitrite, along with a range of saccharides and protein rich substrates. …

Patterns, Processes And Models Of Microbial Recovery In A Chronosequence Following Reforestation Of Reclaimed Mine Soils
… also revealed that lower relative abundances of methanotrophs and methane monooxygenase at previously-mined sites compared with unmined sites, which supports previous observations that ecological function of methane sink provided by many forest soils has not recovered after 30 years. Because of …

Methane-cycling microbial communities in permafrost affected soils on Herschel Island and the Yukon Coast, Western Canadian Arctic
… being dominated by type-II rather than type-I methanotrophs. After being subjected to strong increases in soil temperature, the active-layer microbial community demonstrated the ability to quickly adapt and as a result shifts in community composition could be observed. These results contribute …
