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.

Two proteins, the hydrazine synthase (previously hydrazine hydrolase) and an F‐ATPase, were identified by proteomics and LC‐MS/MS analysis Anaerobic ammonium-oxidizing (anammox) bacteria defy many microbiological concepts and share numerous properties with both eukaryotes and archaea. Among their most intriguing characteristics are their compartmentalized cell plan and archaeon-like cell wall. Here we review our current knowledge about anammox cell biology.

In marine environments, Candidatus Scalindua species were dominant. Screening of wastewater treatment plants usually also detects anammox bacteria, often in biofilms of the nitrifying step. revive the anammox process in a pilot fluidized-bed reac-tor Astrid van de Graaf added (15N)-labelled ammonium to the reactor which was fed unlabelled (14N)-nitrate and to our immense joy the mass spectrometer showed that the majority of the label ended up in mixed labelled 14,15N-N 2 gas (reaction 2A). The reaction immediately The discovery of the Anammox bacteria changed the view of the nitrogen cycle and resul - ted in a remarkably active wastewater treatment research around the world.

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. Reaction products released to the air are highly oxygenated.

The anammox reaction was detected at all sites with its potential contribution to the production of N 2 (ra, %) ranging from <1 to 11%. Overall, a higher con-tribution from anammox was positively correlated with both the concentration of NO 3

anammox, and tdn recycling combined with in situ measurements. and a better understanding of its reaction mechanisms and regulation is  agaric to observe his body's reactions and temp- erature changes.

Anammox 1,2, a process of anaerobic ammonium oxidation, is an innovative technological advancement in the r emoval of ammonia nitrogen in waste water. 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 microorganisms can also directly couple NO reduction to ammonia oxidation, without the need for nitrite supply. Another, still unexplored, reaction mechanism involves anaerobic ammonium oxidation on anodes of bio-electrical systems. Such systems can be microbial fuel cells or microbial electrolysis cells.

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).
