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.

Wetland soil history shapes microbial community composition, while hydrologic disturbance alters greenhouse gas fluxes

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract While wetlands represent a small fraction (~5%–10%) of the world's land surface, it is estimated that one‐third of wetlands have been lost due to human activities. Wetland habitat loss decreases ecosystem benefits, including improved water quality and climate change mitigation.

Draft genome sequence of Methyloferula stellata AR4, an obligate methanotroph possessing only a soluble methane monooxygenase [PDF]

, 2015
Methyloferula stellata AR4 is an aerobic acidophilic methanotroph, which, in contrast to most known methanotrophs but similar to Methylocella spp., possesses only a soluble methane monooxygenase. However, it differs from Methylocella spp.

Thermophilic methanotrophs: in hot pursuit

FEMS Microbiology Ecology, 2019
ABSTRACTMethane is a potent greenhouse gas responsible for 20–30% of global climate change effects. The global methane budget is ∼500–600 Tg y−1, with the majority of methane produced via microbial processes, including anthropogenic-mediated sources such as ruminant animals, rice fields, sewage treatment facilities and landfills.

Epixylic microbial communities as key regulators of methane emissions from submerged wood in a tropical hydroelectric reservoir

Limnology and Oceanography, Volume 71, Issue 3, March 2026.
Abstract Tropical hydroelectric reservoirs are recognized hotspots for greenhouse gas emissions, yet the role of submerged forests in these emissions remains poorly understood. In this study, we investigated the contribution of standing dead trees and their associated epixylic biofilms to methane (CH4) and carbon dioxide (CO2) emissions in the ...

Novel copper-containing membrane monooxygenases (CuMMOs) encoded by alkane-utilizing Betaproteobacteria. [PDF]

, 2020
Copper-containing membrane monooxygenases (CuMMOs) are encoded by xmoCAB(D) gene clusters and catalyze the oxidation of methane, ammonia, or some short-chain alkanes and alkenes.

Mitigating greenhouse gas emissions from a tropical sandy loam using oil palm empty fruit bunch biochar and compost amendments

Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.
Abstract The role of biochar in mitigating greenhouse gas (GHG) emissions from tropical soils, especially when combined with compost, is still not adequately researched. This study evaluated the effects of oil palm empty fruit bunch (EFB) biochar applied at 10 and 20 t ha−1 (B10 and B20), compost at 20 t ha−1 (CP20) and in combination (B10CP20 and ...

Resource availability governs polyhydroxyalkanoate (PHA) accumulation and diversity of methanotrophic enrichments from wetlands

Frontiers in Bioengineering and Biotechnology, 2023
Aquatic environments account for half of global CH4 emissions, with freshwater wetlands being the most significant contributors. These CH4 fluxes can be partially offset by aerobic CH4 oxidation driven by methanotrophs.

A Temporally Consistent Spatial Gradient in Methane Ebullition From a Eutrophic Lake

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Gas bubble emission (ebullition) from lake sediment is a prominent source of the greenhouse gas methane (CH4) to the atmosphere, but the stochastic nature of bubble release and thus high variability in space and time makes the estimation of lake CH4 ebullition challenging.
