While this by itself is thermodynamically possible, it is biochemically impossible. 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. The anammox process occurs under anaerobic conditions by bacterial mediated combination of NO 2 with NH 4. The reaction was first suggested by Richards (1965) and first shown directly to occur in wastewater bioreactors (Mulder et al., 1995). The anammox reaction uses NH 4 produced during oxidation of organic matter required for denitrification.

Performed research confirmed a hypothesis, that the oxygen concentration in the bulk liquid and the nitrite production rate are the limiting factors for the Anammox reaction in a single reactor. Abstract Bacteria performing anaerobic ammonium oxidation (anammox) are key players in the global nitrogen cycle due to their inherent ability to convert biologically available nitrogen to N2. Identification of key proteins involved in the anammox reaction. Anammox is increasingly being exploited during wastewater treatment worldwide, and about 50% of the total N(2) production in marine environments is estimated to proceed by the anammox pathway.

Anammox-Organismen. Von der Theorie schon Jahrzehnte zuvor postuliert, wurde die Anammox-Reaktion erstmals in den 1980ern in einer Abwasserreinigungsanlage in Delft in den Niederlanden beobachtet (Mike Jetten). Verantwortlich dafür ist das bisher wenig beachtete Bakterium Candidatus Brocadia anammoxidans.

Landfill leachate is an enormous problem in the UK with major environmental consequences for pollution, eutrophication and climate change. The aim of this PhD project is to provide a novel solution to ammonium removal from the landfill leachate through the microbially driven anammox (anaerobic ammonium oxidation) reaction.

This new pr ocess combines a m monia and nitrite directly into dinitrogen gas3. The anammox reaction can be repr esented as + + − NH 4 NO 2 = N 2 + 2H O. This reaction is carried out by anammox anammox reaction rates, thereby p roviding a quantitative link be-tween microbial proliferation and energy availability.

The anammox reaction uses NH 4 produced during oxidation of organic matter required for denitrification. The Anammox reaction can be represented as NH 4 - + NO 2 - = N 2 + 2H 2 O. This reaction is carried out by Anammox bacteria (Candidatus Brocadia anammoxidans) belonging to the group of planctomycete (SHIVARAMAN and SHIVARAMAN 2003). Anammox bacteria are chemolithoautotrophs that use the exergonic reaction NH 4 + + NO 2 − → N 2 + 2 H 2 O as the primary source of energy and reductant for autotrophic growth, fixing carbon by the acetyl-CoA pathway. Hydrazine (N 2 H 4) is a free intermediate in the process. Quantitative assays indicate that the anammox reaction is responsible for at least 40%–50% of the total global marine N‐turnover.
