Methane is involved in a number of chemical and physical processes in the Earth's atmosphere, including global warming. Atmospheric methane originates mainly from biogenic sources, such as rice paddies and natural wetlands; the former account for at least 30% of the global annual emission of methane to the atmosphere. As an increase of rice production by 60% is the most appropriate way to sustain the estimated increase of the human population during the next three decades, intensified global… 
Differential Effects of Nitrogenous Fertilizers on Methane-Consuming Microbes in Rice Field and Forest Soils
The results of this study provide a case example showing that microbial community structure indeed matters, especially when assessing and predicting the impact of environmental change on biodiversity loss and ecosystem functioning.
Prospecting the significance of methane-utilizing bacteria in agriculture.
Microorganisms act as both the source and sink of methane, a potent greenhouse gas, thus making a significant contribution to the environment as an important driver of climate change. The rhizosphere
Methanogenesis and Methane Emission in Rice / Paddy Fields
Rice fields are a major source of atmospheric methane (CH4), a greenhouse gas. CH4 emissions from wetland rice fields represents globally 15–20% of the annual anthropogenic CH4 emissions, and about
Effects of Soil Types on Methane Gas Emission in Paddy During Rice Cultivation
Anaerobic decomposition of organic materials in flooded rice fields produces methane () gas, which escapes to the atmosphere primarily by transport through organs of the rice plants such as arenchyma

It has now become possible to isolate, detect and characterize the methanogens and methanotrophs by using molecular biological tools like PCR, FISH, etc.


Fluxes of methane from rice fields and potential for mitigation
Abstract. Methane (CH4) is an important greenhouse gas. Flooded rice fields (paddies) are a significant source of atmospheric CH4; estimates of the annual emission from paddies range from less than
Effect of increasing atmospheric methane concentration on ammonium inhibition of soil methane consumption
SOILS currently consume about 30–40 Tg methane per year1,2, which is comparable to the net annual increase in atmospheric methane concentration from 1980 to 19903. Most soils consume methane2,4–9,
Effects of ammonium-based fertilisation on microbialprocesses involved in methane emission from soilsplanted with rice
The emission of the greenhouse gas CH4 from ricepaddies is strongly influenced by management practicessuch as the input of ammonium-based fertilisers. Weassessed the impact of different levels (200
Influence of nitrogen fertilization on methane uptake in temperate forest soils
METHANE, a long-lived gas (8–10 years residence time), is important in the chemistry of the atmosphere and the Earth's radiation balance1–3. The tropospheric abundance of CH4 has been increasing by

Results of an in vitro assay revealed that root-associated methane consumption was a common attribute of diverse emergent wetland macrophytes from a variety of habitats, and indicated that oxygen availability might be more important than methane as a rate determinant.
Molecular Analyses of the Methane-Oxidizing Microbial Community in Rice Field Soil by Targeting the Genes of the 16S rRNA, Particulate Methane Monooxygenase, and Methanol Dehydrogenase
The DGGE patterns and the sequences of major DGGE bands obtained with the universal SSU rDNA primer set showed that the community structure was dominated by nonmethanotrophic populations related to the genera Flavobacterium andBacillus and was not influenced by CH4.
Spatial distribution and inhibition by ammonium of methane oxidation in intertidal freshwater marshes
The ecological relevance for ammonium inhibition of methane oxidation in intertidal marshes is rather limited and is restricted to the surface layer of the sediment.
Effects of Ammonium and Non-Ammonium Salt Additions on Methane Oxidation by Methylosinus trichosporium OB3b and Maine Forest Soils
Results presented here show that inhibition of methane consumption by non-ammonium salts can be explained in part by ion-exchange reactions: cations desorb ammonium, with the level of desorption varying as a function of both the cation and anion added; differential Desorption results in differential inhibition levels.
