They can use reduced sulfur compounds such as sulfide (H 2S), elemental sulfur (S0), or thiosulfate (S 2O 2{3) as electron donors for the reduction of NO{3 to NO {2 Initially anammox research5 was fo-cused on the basic properties of the pro c-ess and on providing evidence for its microbial nature and the principles of the nitrogen and carbon metabolism. It appears that the anammox process is based on energy conservation from an-oxic am monium oxidation with nitrite as the electron acceptor and hydrazine and An integrated biotrickling filter–anammox bioreactor system for the complete treatment of ammonia in air with conversion to nitrogen gas without the supply of an extraneous electron donor for denitrification was established. Partial nitritation (i.e., conversion of ammonium to nitrite) was successfully achieved in the biotrickling filter (BTF) through free ammonia (FA) and free nitrous acid Anammox coupling with nitrate reduction under various electron donors was studied using sludge acclimatized to have anammox and denitrification : تی پی بین، پایگاه داده های علمی تمام متن In anammox, ammonium is oxidized to N2 strictly under anoxic condition using nitrite as the electron acceptor (Eq. (3)) [5,12,27,28]. Anammox organisms utilize CO2 as the source of car-bon and NO2 − as the electron acceptor for ammonium oxidation. Concurrently, NO2 − is used as the electron donor for the reduc-tion of CO2. genes [ ], containing domains involved in electron transfer and catalysis were detected. 4.
