Methane production and consumption in temperate and subarctic peat soils: Response to temperature and pH
Abstract Rates of methane (CH4) production under anaerobic conditions and CH4 consumption under aerobic conditions were studied in slurries of peat samples kept at different temperatures (0–35°C) andExpand
Diversity and Activity of Methanotrophic Bacteria in Different Upland Soils
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. Expand
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. Expand
Methylocella silvestris sp. nov., a novel methanotroph isolated from an acidic forest cambisol.
The data suggest that strains BL2(T) and A1 represent a novel species of Methylocella; the name Methyla silvestris sp. Expand
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. Expand
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. Expand
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. Expand
Environmental, genomic and taxonomic perspectives on methanotrophic Verrucomicrobia.
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. Expand
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. Expand
High-Affinity Methane Oxidation by a Soil Enrichment Culture Containing a Type II Methanotroph
The data suggest that the affinity of methanotrophic bacteria for CH4 varies with growth conditions and that the oxidation of atmospheric CH4 observed in this soil is carried out by type II methanOTrophic bacteria which are similar to characterized species. Expand
