Anaerobic ammonium oxidation (anammox) in different natural ecosystems.
Anammox (anaerobic ammonium oxidation), which is a reaction that oxidizes ammonium to dinitrogen gas using nitrite as the electron acceptor under anoxic conditions, was an important discovery in the nitrogen cycle. The reaction is mediated by a specialized group of planctomycete-like bacteria that were first discovered in man-made ecosystems. Subsequently, many studies have reported on the ubiq...
متن کاملDiversity of ammonium-oxidizing bacteria in a granular sludge anaerobic ammonium-oxidizing (anammox) reactor.
The ammonium-oxidizing microbial community was investigated in a granular sludge anaerobic ammonium-oxidizing (anammox) reactor that was operated for about 1 year with high anaerobic ammonium oxidation activity (up to 0.8 kg NH(4)(+)-N m(-3) day(-1)). A Planctomycetales-specific 16S rRNA gene library was constructed to analyse the diversity of the anaerobic ammonium-oxidizing bacteria (AnAOB). ...
متن کاملBiological Nitrogen Removal Using Anaerobic Ammonium Oxidation
ANaerobic AMMonium OXidation (Anammox) is an efficient microbiological process for the removal of ammonia nitrogen from wastewater. Although several Anammox reactors have been operated successfully in European water pollution control plants, there are challenges associated with the process which must be addressed to ensure dependable performance when treating high strength wastestreams in New Y...
متن کاملEffects of substrates on N2O emissions in an anaerobic ammonium oxidation (anammox) reactor
N2O emission in the anaerobic ammonium oxidation (anammox) process is of growing concern. In this study, effects of substrate concentrations on N2O emissions were investigated in an anammox reactor. Extremely high N2O emissions of 1.67 % were led by high NH4-N concentrations. Results showed that N2O emissions have a positive correlation with NH4-N concentrations in the anammox reactor. Reducing...
متن کاملStart-up of Anaerobic Ammonium Oxidation (Anammox) from Conventional Return Activated Sludge in Up-flow Anaerobic Sludge Blanket (UASB) Reactor for Autotrophic Nitrogen Removal from Wastewater
A bench-scale up-flow anaerobic sludge blanket (UASB) reactor was applied to start-up the anaerobic ammonium oxidation (Anammox) process from conventional return activated sludge. The reactor was operated for approximately 170 days and was fed synthetic wastewater containing mainly nitrite ) (NO2 − and ammonium ) (NH 4 + as main substrates. After 106 days of operation, the first evidence of Ana...
