Nitric Oxide Dismutase (nod) Genes as a Functional Marker for the Diversity and Phylogeny of Methane-Driven Oxygenic Denitrifiers

Frontiers in Microbiology, 2019
Oxygenic denitrification represents a new route in reductive nitrogen turnover which differs from canonical denitrification in how nitric oxide (NO) is transformed into dinitrogen gas.

Methanotrophs from natural ecosystems as biocontrol agents for ruminant methane emissions [PDF]

, 2012
In ruminant cattle, the anaerobic fermentation of ingested plant biomass results in the production of methane (CH4). This CH4 is subsequently eructated to the environment, where it acts as a potent greenhouse gas and is one of the leading sources of ...

Isoprene Production by Sphagnum Moss Is Balanced by Microbial Uptake, as Revealed by Selective Inhibitors

Environmental Microbiology, Volume 27, Issue 6, June 2025.
Sphagnum moss, typical of northern peatlands, produces a range of volatile organic compounds, principally the climate‐active compound, isoprene, which serves as a carbon source for specialist isoprene‐consuming microbes. Using an inhibitor of microbial isoprene uptake, we quantify gross isoprene production by the moss and show that the vast majority of

Methane Elimination Using Biofiltration Packed With Fly Ash Ceramsite as Support Material

Frontiers in Bioengineering and Biotechnology, 2020
Methane is a greenhouse gas and significantly contributes to global warming. Methane biofiltration with immobilized methane-oxidizing bacteria (MOB) is an efficient and eco-friendly approach for methane elimination.

Genomic Reconstruction of an Uncultured Hydrothermal Vent Gammaproteobacterial Methanotroph (Family Methylothermaceae) Indicates Multiple Adaptations to Oxygen Limitation [PDF]

, 2015
Hydrothermal vents are an important contributor to marine biogeochemistry, producing large volumes of reduced fluids, gasses, and metals and housing unique, productive microbial and animal communities fueled by chemosynthesis.

Environmental Gradients and Conservation Status Determine the Structure and Carbon‐Related Metabolic Potential of the Prokaryotic Communities of Mediterranean Inland Saline Shallow Lakes

Ecology and Evolution, Volume 15, Issue 5, May 2025.
Mediterranean inland saline shallow lakes are divided into different categories according to their salinity and conservation status, which determine the structuration of the prokaryotic communities and their carbon‐related metabolisms. ABSTRACT Mediterranean inland saline lakes may play an important role in the carbon cycle due to the metabolic ...

Probe Capture Enrichment Sequencing of amoA Genes Improves the Detection of Diverse Ammonia‐Oxidising Archaeal and Bacterial Populations

Molecular Ecology Resources, Volume 25, Issue 3, April 2025.
ABSTRACT The ammonia monooxygenase subunit A (amoA) gene has been used to investigate the phylogenetic diversity, spatial distribution and activity of ammonia‐oxidising archaeal (AOA) and bacterial (AOB), which contribute significantly to the nitrogen cycle in various ecosystems. Amplicon sequencing of amoA is a widely used method; however, it produces

Resistance and Recovery of Methane-Oxidizing Communities Depends on Stress Regime and History; A Microcosm Study

Frontiers in Microbiology, 2018
Although soil microbes are responsible for important ecosystem functions, and soils are under increasing environmental pressure, little is known about their resistance and resilience to multiple stressors.

Microbial Ecology of Methanotrophy in Streams Along a Gradient of CH4 Availability

Frontiers in Microbiology, 2020
Despite the recognition of streams and rivers as sources of methane (CH4) to the atmosphere, the role of CH4 oxidation (MOX) in these ecosystems remains poorly understood to date.

Controlling Methane Ebullition Flux in Cascade Reservoirs of the Upper Yellow River by the Ratio of mcrA to pmoA Genes

Water
Reservoirs are an important source of methane (CH4) emissions, but the relative contribution of CH4 ebullition and diffusion fluxes to total fluxes has received little attention in the past. In this study, we systematically monitored the CH4 fluxes of nine cascade reservoirs (Dahejia, Jishixia, Huangfeng, Suzhi, Kangyang, Zhiganglaka, Lijiaxia, Nina ...
