Anaerobic oxidization of methane in a minerotrophic peatland: enrichment of nitrite-dependent methane-oxidizing bacteria.
The importance of anaerobic oxidation of methane (AOM) as a methane sink in freshwater systems is largely unexplored, particularly in peat ecosystems. Nitrite-dependent anaerobic methane oxidation (n-damo) was recently discovered and reported to be catalyzed by the bacterium "Candidatus Methylomirabilis oxyfera," which is affiliated with the NC10 phylum. So far, several "Ca. Methylomirabilis ox...
متن کاملCo-occurrence and distribution of nitrite-dependent anaerobic ammonium and methane-oxidizing bacteria in a paddy soil.
The anaerobic ammonium-oxidizing (anammox) and nitrite-dependent anaerobic methane-oxidizing (n-damo) bacteria in a paddy soil core (0-100 cm) were investigated with newly designed primers targeting the hydrazine synthase β-subunit (hzsB) of anammox bacteria and the recently published primers targeting the pmoA and 16S rRNA genes of n-damo bacteria. The hzsB gene was identified as a proper biom...
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 کاملSimultaneous nitrite-dependent anaerobic methane and ammonium oxidation processes.
Nitrite-dependent anaerobic oxidation of methane (n-damo) and ammonium (anammox) are two recently discovered processes in the nitrogen cycle that are catalyzed by n-damo bacteria, including "Candidatus Methylomirabilis oxyfera," and anammox bacteria, respectively. The feasibility of coculturing anammox and n-damo bacteria is important for implementation in wastewater treatment systems that cont...
متن کاملAnaerobic oxidation of methane: an underappreciated aspect of methane cycling in peatland ecosystems?
Despite a large body of literature on microbial anaerobic oxidation of methane (AOM) in marine sediments and saline waters and its importance to the global methane (CH4) cycle, until recently little work has addressed the potential occurrence and importance of AOM in non-marine systems. This is particularly true for peatlands, which represent both a massive sink for atmospheric CO2 and a signif...
