Denitrification coupled with methane anoxic oxidation and microbial community involved identification [PDF]

, 2011
In this work, the biological denitrification associated with anoxic oxidation of methane and the microbial diversity involved were studied. Kinetic tests for nitrate (NO3-) and nitrite (NO2-) removal and methane uptake were carried out in 100 mL batch ...

Perspectives for Advancing Biotechnological Succinic Acid Production

Microbial Biotechnology, Volume 19, Issue 5, May 2026.
Succinic acid is an important molecule for sustainable chemical manufacturing, but its industrial production faces high costs and sustainability challenges, which are linked to feedstocks and excessive acid/base consumption. This opinion explores production routes based on next‐generation feedstocks and low‐pH fermentations to inspire novel cost ...

Using Radon (222Rn) to Trace Variability in Greenhouse Gas Emission From Tree Stems Across Species, Seasons and Stem Heights

Ecohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Emissions from trees are an important component of the global methane (CH4) cycle, but their spatial origins (soil vs. in‐stem), transport pathways and environmental influences are not well constrained. To address these issues, this field study characterized spatial and temporal variability in stem emissions of biologically inert radon (222Rn),

Nitrification-denitrification in WSP: a mechanism for permanent nitrogen removal in maturation ponds [PDF]

, 2009
A pilot-scale primary maturation pond was spiked with 15N-labelled ammonia (15NH4Cl) and 15N labelled nitrite (Na15NO2), in order to improve current understanding of the dynamics of inorganic nitrogen transformations and removal in WSP systems.

Facultative methanotrophs are abundant at terrestrial natural gas seeps [PDF]

, 2018
Background: Natural gas contains methane and the gaseous alkanes ethane, propane and butane, which collectively influence atmospheric chemistry and cause global warming.

Kinetics of sulfate‐ and iron‐dependent anaerobic methane oxidation in freshwater lake sediment

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Anaerobic oxidation of methane (AOM) is a potentially important sink for methane in freshwater sediments. Assessing the contribution of AOM to methane budgets requires an understanding of AOM process kinetics, yet such information remains scarce.

High resolution depth distribution of Bacteria, Archaea, methanotrophs, and methanogens in the bulk and rhizosphere soils of a flooded rice paddy

Frontiers in Microbiology, 2015
The communities and abundances of methanotrophs and methanogens, along with the oxygen, methane, and total organic carbon (TOC) concentrations, were investigated along a depth gradient in a flooded rice paddy.

Understanding methanotroph ecology in a biofilter for efficiently mitigating methane emissions : a thesis presented in fulfilment of the requirements for the degree of Doctor of Philosophy in Soil Science (Biotechnology) at Massey University, Palmerston North, New Zealand [PDF]

, 2016
In New Zealand, the majority of the greenhouse gas (GHG), methane (CH4) emissions are from the agriculture sector (enteric fermentation, manure management) and the remainder from solid waste disposal, coal mining and natural gas leaks.

Bridging the Gap From Peat to Ponds: Terrestrial and Aquatic Greenhouse Gas Emissions in an Evolving Permafrost‐Associated Subarctic Peatland

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract Rapid permafrost thaw in peatlands transforms the subarctic landscape into a mosaic of ponds and peat soil, varying in moisture, carbon and nutrients, and time since thaw. As subarctic permafrost degrades, ponds emerge and mature and can gradually infill with Sphagnum peat.

Methanotrophic activity and diversity of methanotrophs in volcanic-geothermal soils at Pantelleria island (Italy) [PDF]

, 2014
Volcanic and geothermal systems emit endogenous gases by widespread degassing from soils, including CH4, a greenhouse gas twenty-five times as potent as CO2.
