Anaerobic oxidation of methane: an “active” microbial process
The anaerobic oxidation of methane (AOM) is an important sink of methane that plays a significant role in global warming. AOM was first found to be coupled with sulfate reduction and mediated by anaerobic methanotrophic archaea (ANME) and sulfate-reducing bacteria (SRB). ANME, often forming consortia with SRB, are phylogenetically related to methanogenic archaea. ANME-1 is even able to produce ...
متن کاملEvidence for nitrite-dependent anaerobic methane oxidation as a previously overlooked microbial methane sink in wetlands.
The process of nitrite-dependent anaerobic methane oxidation (n-damo) was recently discovered and shown to be mediated by "Candidatus Methylomirabilis oxyfera" (M. oxyfera). Here, evidence for n-damo in three different freshwater wetlands located in southeastern China was obtained using stable isotope measurements, quantitative PCR assays, and 16S rRNA and particulate methane monooxygenase gene...
متن کاملNew 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...
متن کاملAnaerobic 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...
متن کاملAnaerobic 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...
