Anaerobic methane oxidation by nitrate: kinetic isotope effect

A Metagenomics-Based Metabolic Model of Nitrate-Dependent Anaerobic Oxidation of Methane by Methanoperedens-Like Archaea

Methane oxidation is an important process to mitigate the emission of the greenhouse gas methane and further exacerbating of climate forcing. Both aerobic and anaerobic microorganisms have been reported to catalyze methane oxidation with only a few possible electron acceptors. Recently, new microorganisms were identified that could couple the oxidation of methane to nitrate or nitrite reduction...

Study of the Anaerobic Methane Oxidation Coupled to Nitrate Denitrification by

New perspectives on anaerobic methane oxidation.

Anaerobic methane oxidation is a globally important but poorly understood process. Four lines of evidence have recently improved our understanding of this process. First, studies of recent marine sediments indicate that a consortium of methanogens and sulphate-reducing bacteria are responsible for anaerobic methane oxidation; a mechanism of 'reverse methanogenesis' was proposed, based on the pr...

Anaerobic methane oxidation and denitrification as methane sink

Early social exposure is important for developing appropriate, species-specific adult behaviors. Carson Murray et al. (pp. 18189–18194) followed wild chimpanzees, habituated to human observers, in Gombe National Park, Tanzania, and analyzed maternal subgrouping patterns to investigate why adult males tend to be more gregarious than adult females. Mothers accompanied by their sons were more greg...

Anaerobic methane oxidation in Black Sea sediments

Anaerobic oxidation of methane (AOM) and sulfate reduction (SRR) were investigated in sediments of the western Black Sea, where methane transport is controlled by diffusion. To understand the regulation and dynamics of methane production and oxidation in the Black Sea, rates of methanogenesis, AOM, and SRR were determined using ra-5 diotracers in combination with pore water chemistry and stable...
