Soil Properties Interacting With Microbial Metagenome in Decreasing CH4 Emission From Seasonally Flooded Marshland Following Different Stages of Afforestation

Frontiers in Microbiology, 2022
Wetlands are the largest natural source of terrestrial CH4 emissions. Afforestation can enhance soil CH4 oxidation and decrease methanogenesis, yet the driving mechanisms leading to these effects remain unclear.

Water table level controls methanogenic and methanotrophic communities and methane emissions in a Sphagnum-dominated peatland

Microbiology Spectrum, 2023
Peatlands are important sources of the greenhouse gas methane emissions equipoised by methanogens and methanotrophs. However, knowledge about how microbial functional groups associated with methane production and oxidation respond to water table ...

Compound Microbial Agent Improves Soil Redox Status to Reduce Methane Emissions from Paddy Fields

Rice Science
Paddy fields are considered a major source of methane (CH4) emissions. Aerobic irrigation methods have proven to be efficacious in mitigating CH4 emissions in paddy cultivation. The promising role of compound microbial agents in refining the rhizospheric

Aquatic plant surface as a niche for methanotrophs

Frontiers in Microbiology, 2014
This study investigated the potential local CH4 sink in various plant parts as a boundary environment of CH4 emission and consumption. By comparing CH4 consumption activities in cultures inoculated with parts from 39 plant species, we observed ...

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

Biochemical Engineering Journal, 2017
Abstract 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 ...

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.

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.

Characterization of C ₁ -Metabolizing Prokaryotic Communities in Methane Seep Habitats at the Kuroshima Knoll, Southern Ryukyu Arc, by Analyzing pmoA , mmoX , mxaF , mcrA , and 16S rRNA Genes [PDF]

Applied and Environmental Microbiology, 2004
ABSTRACT Samples from three submerged sites (MC, a core obtained in the methane seep area; MR, a reference core obtained at a distance from the methane seep; and HC, a gas-bubbling carbonate sample) at the Kuroshima Knoll in the southern Ryuku arc were analyzed to gain insight into the organisms present and the processes involved

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 ...
