Journal ArticleDOI
Anaerobic ammonium oxidation discovered in a denitrifying fluidized bed reactor
TL;DR: Anaerobic ammonium oxidation is a new process in which ammonium is oxidized with nitrate serving as the electron acceptor under anaerobic conditions, producing dinitrogen gas, and has been given the name ‘Anammox’ (anaerobic ammonia oxidation), and has be patented.
Journal ArticleDOI
Autotrophic growth of anaerobic ammonium-oxidizing micro-organisms in a fluidized bed reactor
TL;DR: An autotrophic, synthetic medium for the enrichment of anaerobic ammonium-oxidizing (Anammox) micro-organisms was developed and Acetylene, phosphate and oxygen were shown to be strong inhibitors of the Anammox activity.
Journal ArticleDOI
Anaerobic oxidation of ammonium is a biologically mediated process
TL;DR: It was concluded that anaerobic ammonium oxidation was a microbiological process as the conversion of ammonium to dinitrogen gas did not even require a trace of O2.
Journal ArticleDOI
Aerobic denitrification: a controversy revived
Lesley A. Robertson,J.G. Kuenen +1 more
TL;DR: During studies on the denitrifying mixotroph, Thiosphaera pantotropha, it has been found that this organism is capable of simultaneously utilizing nitrate and oxygen as terminal electron acceptors in respiration.
Journal ArticleDOI
Simultaneous Nitrification and Denitrification in Aerobic Chemostat Cultures of Thiosphaera pantotropha
TL;DR: It appeared that, under carbon-and energy-limited conditions, a high nitrification rate was correlated with a reduced biomass yield, and several species considered to be "poor" nitrifiers also simultaneously nitrify and denitrify, thus giving a falsely low nitrification potential.
