Enrichment of Denitrifying Methane-Oxidizing Microorganisms Using Up-Flow Continuous Reactors and Batch Cultures
Denitrifying anaerobic methane oxidizing (DAMO) microorganisms were enriched from paddy field soils using continuous-flow and batch cultures fed with nitrate or nitrite as a sole electron acceptor. After several months of cultivation, the continuous-flow cultures using nitrite showed remarkable simultaneous methane oxidation and nitrite reduction and DAMO bacteria belonging to phylum NC10 were ...
متن کاملAnaerobic ammonium-oxidizing bacteria: unique microorganisms with exceptional properties.
Anaerobic ammonium-oxidizing (anammox) bacteria defy many microbiological concepts and share numerous properties with both eukaryotes and archaea. Among their most intriguing characteristics are their compartmentalized cell plan and archaeon-like cell wall. Here we review our current knowledge about anammox cell biology. The anammox cell is divided into three separate compartments by bilayer me...
متن کاملDevelopment of High-Rate Anaerobic Ammonium-Oxidizing
1 To promptly establish anammox (anaerobic ammonium oxidation) reactors, appropriate 2 seeding sludge with high abundance and activity of anammox bacteria was selected by 3 quantifying 16S rRNA gene copy numbers of anammox bacteria by real-time quantitative 4 PCR (RTQ-PCR) and batch culture experiments. The selected sludge was then inoculated into 5 up-flow fixed-bed biofilm column reactors wit...
متن کاملAnaerobic 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 کاملDistribution of putative denitrifying methane oxidizing bacteria in sediment of a freshwater lake, Lake Biwa.
Methane oxidation coupled to denitrification is mediated by 'Candidatus Methylomirabilis oxyfera', which belongs to the candidate phylum NC10. The distribution of putative denitrifying methane-oxidizing bacteria related to "M. oxyfera" was investigated in a freshwater lake, Lake Biwa, Japan. In the surface layer of the sediment from a profundal site, a phylotype closely related to "M. oxyfera" ...
