Alpha- and Gammaproteobacterial Methanotrophs Codominate the Active Methane-Oxidizing Communities in an Acidic Boreal Peat Bog [PDF]

, 2016
The objective of this study was to characterize metabolically active, aerobic methanotrophs in an ombrotrophic peatland in the Marcell Experimental Forest, Minnesota, USA.

Methane-Oxidizing Communities in Lichen-Dominated Forested Tundra Are Composed Exclusively of High-Affinity USCα Methanotrophs

Microorganisms, 2020
Upland soils of tundra function as a constant sink for atmospheric CH4 but the identity of methane oxidizers in these soils remains poorly understood. Methane uptake rates of −0.4 to −0.6 mg CH4-C m−2 day−1 were determined by the static chamber method in

Identification of Novel Methane-, Ethane-, and Propane-Oxidizing Bacteria at Marine Hydrocarbon Seeps by Stable Isotope Probing [PDF]

, 2010
Marine hydrocarbon seeps supply oil and gas to microorganisms in sediments and overlying water. We used stable isotope probing (SIP) to identify aerobic bacteria oxidizing gaseous hydrocarbons in surface sediment from the Coal Oil Point seep field ...

Niche differentiation in nitrogen metabolism among methanotrophs within an operational taxonomic unit [PDF]

, 2014
Background: The currently accepted thesis on nitrogenous fertilizer additions on methane oxidation activity assumes niche partitioning among methanotrophic species, with activity responses to changes in nitrogen content being dependent on the in situ ...

Erratum to: A novel pmoA lineage represented by the acidophilic methanotrophic bacterium Methylocapsa acidophila B2 [PDF]

Archives of Microbiology, 2001
A fragment of the functional gene pmoA, which encodes the active-site polypeptide of particulate methane monooxygenase (pMMO), was PCR-amplified from DNA of the recently described acidophilic methanotrophic bacterium Methylocapsa acidophila B2. This methanotroph was isolated from an acidic Sphagnum peat bog and possesses a novel type III arrangement of

Thirty years of arctic primary marine organic aerosols: patterns, seasonal dynamics, and trends (1990–2019) [PDF]

Atmospheric Chemistry and Physics
Changing Arctic climate conditions have accelerated sea ice retreat, altering ocean–atmosphere interactions and marine ecosystems. Reduced sea ice cover likely enhances emissions of primary marine organic aerosol (PMOA) through bubble bursting, with ...

Effect of different types of biochar on soil properties and functional microbial communities in rhizosphere and bulk soils and their relationship with CH4 and N2O emissions

Frontiers in Microbiology, 2023
Biochar as an agricultural soil amendment plays vital roles in mediating methane (CH4) and nitrous oxide (N2O) emissions in soils. The link between different types of biochar, bulk soil, and rhizosphere microbial communities in relation to CH4 and N2O ...

A temperate river estuary is a sink for methanotrophs adapted to extremes of pH, temperature and salinity [PDF]

, 2016
River Tyne (UK) estuarine sediments harbour a genetically and functionally diverse community of methane-oxidizing bacteria (methanotrophs), the composition and activity of which were directly influenced by imposed environmental conditions (pH, salinity ...

Spatial Heterogeneity in Methane Biogeochemistry and Prokaryotic Community Structure in Sub-Arctic Waterbodies in Northern Canada. [PDF]

Environ Microbiol
Prokaryotic communities and methane dynamics differed markedly across 16 sub‐Arctic waterbodies. Maximum depth and permafrost thaw emerged as key drivers, with non‐stratified thaw‐affected sites hosting distinct communities and elevated methane fluxes, highlighting their potential role as emerging hotspots of methane emissions.

Demonstration of a multi-technique approach to assess glacial microbial populations in the field [PDF]

, 2016
The ability to perform microbial detection and characterization in-field at extreme environments, rather than on returned samples, has the potential to improve the efficiency, relevance and quantity of data from field campaigns.
