Classification of pmoA amplicon pyrosequences using BLAST and the lowest common ancestor method in MEGAN [PDF]

, 2014
The classification of high-throughput sequencing data of protein-encoding genes is not as well established as for 16S rRNA. The objective of this work was to develop a simple and accurate method of classifying large datasets of pmoA sequences, a common ...

Methanotrophic community composition based on pmoA genes in dissolved methane recovery and biological oxidation closed downflow hanging sponge reactors

Biochemical Engineering Journal, 2017
Dissolved methane in the effluent of anaerobic wastewater treatment processes is unrecovered and released into the atmosphere as methane, a greenhouse gas. To prevent methane emissions from effluent, a post-treatment system consisting of two closed downflow hanging sponge (DHS) reactors for the recovery and biological oxidation of dissolved methane was

Environmental and microbial factors influencing methane and nitrous oxide fluxes in Mediterranean cork oak woodlands: trees make a difference

Frontiers in Microbiology, 2015
Cork oak woodlands (montado) are agroforestry systems distributed all over the Mediterranean basin with a very important social, economic and ecological value.

Patterns and geographical drivers for the abundance of CO2-assimilating bacteria, methanotrophs and CO-oxidizing bacteria in agricultural soils across eastern China

Journal of Integrative Agriculture
Microorganisms carrying cbbL, pmoA and coxL genes play crucial roles in regulating soil-atmosphere exchanges of carbon trace gases (CO2, CH4, and CO). However, the geographical distribution patterns of these functional genes in agricultural ecosystems ...

Recurrence and frequency of disturbance have cumulative effect on methanotrophic activity, abundance, and community structure.

Frontiers in Microbiology, 2016
Alternate prolonged drought and heavy rainfall is predicted to intensify with global warming. Desiccation-rewetting events alter the soil quality and nutrient concentrations which drive microbial-mediated processes, including methane oxidation, a key ...

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.

Mechanistic role of biochar as a geobiochemical amendment: Mitigating abiotic stress and enhancing soil–plant interactions

Soil Science Society of America Journal, Volume 90, Issue 5, September/October 2026.
Abstract Abiotic stressors, including drought, salinity, and heavy metal contamination, pose escalating threats to global food security, challenges further exacerbated by climate change and progressive soil degradation. As a strategic geochemical amendment, biochar is increasingly proposed to enhance soil resilience and agricultural sustainability ...

Effects of Fallow Season Water and Straw Management on Methane Emissions and Associated Microorganisms

Agronomy
The effects of fallow season water and straw management on methane (CH4) emissions during the fallow season and the subsequent rice-growing season are rarely reported, and the underlying microbial mechanisms remain unclear.

Transitioning From Rice‐Wheat to Diversified Rice‐Based Rotations Enhances Rice Production and Mitigates Greenhouse Gas Emissions Across Asia

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Rice‐wheat cropping systems underpin food security across Asia but also represent major sources of agricultural greenhouse gas (GHG) emissions. Replacing wheat with diversified crop species to create alternative rice‐based cropping systems may become an effective strategy for sustainable production.

Inhibition of methane oxidation by nitrogenous fertilizers in a paddy soil

Frontiers in Microbiology, 2012
Nitrogenous fertilizers are generally thought to have an important role in regulating methane oxidation. In this study, the effect of ammonium on methane oxidation activity was investigated in a paddy soil using urea at concentrations of 0, 50, 100, 200 ...
