Anammox--growth physiology, cell biology, and metabolism.
Anaerobic ammonium-oxidizing (anammox) bacteria are the last major addition to the nitrogen-cycle (N-cycle). Because of the presumed inert nature of ammonium under anoxic conditions, the organisms were deemed to be nonexistent until about 15 years ago. They, however, appear to be present in virtually any anoxic place where fixed nitrogen (ammonium, nitrate, nitrite) is found. In various mar`ine...
متن کاملMetagenome of the Microbial Community of Anammox Granules in a Nitritation/Anammox Wastewater Treatment System
We sequenced the metagenome of a granular sludge in a nitritation/anammox bioreactor used for the treatment of ammonium-rich wastewater. Proteobacteria, Planctomycetes, Bacteroidetes, Chloroflexi, Ignavibacteriae, and Acidobacteria were the predominant phyla in the studied bioreactor. Binning of contigs yielded a near-complete genome of the dominant anammox bacterium assigned to the candidate g...
متن کاملEnriquecimento de bactérias anaeróbias oxidadoras de amônia – Anammox Enrichment of anaerobic ammonium oxidizing bacteria – Anammox
Anaerobic ammonium-oxidizing (Anammox) bacteria were enriched from sludge collected at a conventional activated sludge system treating domestic wastewater of Belo Horizonte(MG), Brazil, employing a sequencing batch reactor (SBR). After three months of cultivation, Anammox activity was detected in the system by the consumption of stoichiometric amounts of NO2 and NH4 +. Fluorescent in situ hybri...
متن کاملEffect of zinc on anammox activity and performance of simultaneous partial nitrification, anammox and denitrification (SNAD) process.
In the present study, short-term effects of zinc on anammox activities and long-term effect of zinc on the performance of simultaneous partial nitrification, anammox and denitrification (SNAD) process were evaluated. The anammox activity decreased with increasing zinc concentration and exposure time in short-term tests. The IC50 value of zinc was found to be 6.9mg/L. However, the presence of zi...
متن کاملEffect of nitric oxide on anammox bacteria.
The effects of nitrogen oxides on anammox bacteria are not well known. Therefore, anammox bacteria were exposed to 3,500 ppm nitric oxide (NO) in the gas phase. The anammox bacteria were not inhibited by the high NO concentration but rather used it to oxidize additional ammonium to dinitrogen gas under conditions relevant to wastewater treatment.
