Anaerobic ammonium-oxidizing (anammox) bacteria are responsible for a significant portion of the loss of fixed nitrogen from the oceans, making them important players in the global nitrogen cycle. To date, marine anammox bacteria found in marine water columns and sediments worldwide belong almost exclusively to the 'Candidatus Scalindua' species, but the molecular basis of their metabolism and ...
Abstract Enough biomass of anaerobic ammonium oxidation (anammox) bacteria is essential for maintaining a stable partial nitrification/anammox (PN/A) wastewater treatment system. Present enrichment procedures are mainly labor-intensive and inconvenient up-scaling. A simplified procedure was developed anammox biofilm by using secondary effluent as source water with no supplement mineral medium u...
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...
EXTENDED ABSTRACT The City College of New York (CCNY) in collaboration with New York City Environmental Protection (NYCEP) is currently engaged in operating a 1700 gallon pilot single stage partial nitritation/anaerobic ammonium oxidation (anammox) moving bed biofilm reactor (MBBR) at the 26th Ward waste water treatment plant (WWTP) in Brooklyn, NY. The MBBR is designed to remove nitrogen from ...
Evaluating Primers for Profiling Anaerobic Ammonia Oxidizing Bacteria within Freshwater Environments
Anaerobic ammonia oxidizing (anammox) bacteria play an important role in transforming ammonium to nitrogen gas and contribute to fixed nitrogen losses in freshwater environments. Understanding the diversity and abundance of anammox bacteria requires reliable molecular tools, and these are not yet well established for these important Planctomycetes. To help validate PCR primers for the detection...
