The data indicate that different MB are present and active in different soils that oxidize atmospheric methane, and a novel group of sequences distantly related to those of known type I MB (Gammaproteobacteria) was often detected.
Methane oxidation by an extremely acidophilic bacterium of the phylum Verrucomicrobia
The findings show that methanotrophy in the Bacteria is more taxonomically, ecologically and genetically diverse than previously thought, and that previous studies have failed to assess the full diversity of meethanotrophs in acidic environments.

The data suggest that strains BL2(T) and A1 represent a novel species of Methylocella; the name Methyla silvestris sp.
Methylocella Species Are Facultatively Methanotrophic
The data demonstrate that not all methanotrophic bacteria are limited to growing on one-carbon compounds, which could have major implications for understanding the factors controlling methane fluxes in the environment.

The isolation of thermoacidophilic methanotrophs that represented a distinct lineage within the bacterial phylum Verrucomicrobia are described, and a new genus Methylacidiphilum is proposed to encompass all three newly discovered bacteria.
Isolation of novel bacteria, including a candidate division, from geothermal soils in New Zealand.
The results indicate that geothermal soils are a rich potential source of novel bacteria, and that relatively simple cultivation techniques are practical for isolating bacteria from these habitats.
Kinetics of inhibition of methane oxidation by nitrate, nitrite, and ammonium in a humisol
Soil slurries exhibited nearly standard Michaelis-Menten kinetics, and NaNO(inf3) was a noncompetitive inhibitor of CH(inf4) oxidation, but inhibition was evident only at >10 mM concentrations, which also altered soil pHs.
Response and adaptation of different methanotrophic bacteria to low methane mixing ratios.
Some cultivated methanotrophic bacteria are much more oligotrophic than others, and may contribute to atmospheric methane oxidation in soils, however, it is likely that these need additional energy sources for long-term survival, and that uncultivated groups of methanosinus and Methylobacter are primarily responsible for the process in soils possessing high methane oxidation rates.

This study suggests that USC alpha and Cluster I methanotrophs are adapted to the low concentration of methane in forest soils by possessing high cell-specific CH4 oxidation activities.
