Defining the Sphagnum Core Microbiome across the North American Continent Reveals a Central Role for Diazotrophic Methanotrophs in the Nitrogen and Carbon Cycles of Boreal Peatland Ecosystems

mBio, 2022
Peat mosses of the genus Sphagnum are ecosystem engineers that frequently predominate over photosynthetic production in boreal peatlands. Sphagnum spp.

A Novel Laboratory-Scale Mesocosm Setup to Study Methane Emission Mitigation by Sphagnum Mosses and Associated Methanotrophs

Frontiers in Microbiology, 2021
Degraded peatlands are often rewetted to prevent oxidation of the peat, which reduces CO2 emission. However, the created anoxic conditions will boost methane (CH4) production and thus emission.

Methanotrophy induces nitrogen fixation during peatland development [PDF]

Proceedings of the National Academy of Sciences, 2013
SignificanceIn peatlands, the external sources of nitrogen are mainly atmospheric, but the atmospheric nitrogen deposition alone cannot explain the long-term annual nitrogen accumulation rates to these ecosystems. Because of methodological problems, methane-induced fixation of atmospheric dinitrogen gas has been previously overlooked as an additional ...

The origin of aerobic methanotrophy within the Proteobacteria [PDF]

FEMS Microbiology Letters, 2019
ABSTRACTAerobic methanotrophs play critical roles in the global carbon cycle, but despite their environmental ubiquity, they are phylogenetically restricted. Via bioinformatic analyses, it is shown that methanotrophy likely arose from methylotrophy from the lateral gene transfer of either of the two known forms of methane monooxygenase (particulate and

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.

Microbial Community Dynamics in Early Tufa Biofilms. [PDF]

Microbiologyopen
Microbial succession shapes the early development of tufa biofilms in karst freshwater systems, with prokaryotic communities stabilizing rapidly and microeukaryotes contributing to extracellular polymeric substance production and carbonate entrapment. Site‐specific hydrodynamics and organic inputs drive community specialization, ultimately influencing ...

Planktonic and sediment-associated aerobic methanotrophs in two seep systems along the North American margin [PDF]

, 2008
Methane vents are of significant geochemical and ecological importance. Notable progress has been made towards understanding anaerobic methane oxidation in marine sediments, however, the diversity and distribution of aerobic methanotrophs in the water ...

Difluoromethane, a New and Improved Inhibitor of Methanotrophy [PDF]

Applied and Environmental Microbiology, 1998
ABSTRACT Difluoromethane (HFC-32; DFM) is compared to acetylene and methyl fluoride as an inhibitor of methanotrophy in cultures and soils. DFM was found to be a reversible inhibitor of CH 4 oxidation by Methylococcus capsulatus (Bath). Consumption of CH 4 in

Methane monooxygenases: central enzymes in methanotrophy with promising biotechnological applications [PDF]

World Journal of Microbiology and Biotechnology, 2021
AbstractWorldwide, the use of methane is limited to generating power, electricity, heating, and for production of chemicals. We believe this valuable gas can be employed more widely. Here we review the possibility of using methane as a feedstock for biotechnological processes based on the application of synthetic methanotrophs.

Adapting Macroecology to Microbiology: Using Occupancy Modeling To Assess Functional Profiles across Metagenomes

mSystems, 2021
Metagenomic sequencing provides information on the metabolic capacities and taxonomic affiliations for members of a microbial community. When assessing metabolic functions in a community, missing genes in pathways can occur in two ways; the genes may ...
