Anaerobic ammonium oxidation (anammox) bacteria, which combine ammonium and nitrite or nitrate to form nitrogen gas, were discovered in the early 1990s. 2012-09-01 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 w ….

The big surprise was the serendipitous discovery of the ‘anammox’‐process, whereby ammonium is anaerobically oxidized to dinitrogen gas with nitrite as electron acceptor. The early days of our anammox research are the main focus of this article, which describes the struggle of growing and identifying the most peculiar bacteria we ever came across.

Anammox was discovered in 1995 in a wastewater treatment plant in Delft (NL), but now it is clear that it is the main nitrogen cycle process that contributes up to 50% to the removal of fixed nitrogen in the oceans. However, anammox bacteria grow very slowly, with only about 15 generations per year. Anammox stands for Anaerobic Ammonium Oxidation. The process was discovered in the early nineties and has great potential for the removal of ammonia nitrogen in wastewater. The responsible bacteria transform ammonium (NH4+) and nitrogen dioxide (NO2) into nitrogen gas (N2) and water (H2O).

The bacteria mediating this process were identified in 1999, and were a great surprise for the scientific community. Anammox is an oxidative process and there appear to be some enzymatic similarities between anammox and aerobic NH 3 oxidation (Strous et al., 2006), the ecological significance of anammox is the same as denitrification, i.e., the loss of fixed N in anoxic environments. Anaerobic ammonium oxidation (anammox) bacteria, which combine ammonium and nitrite or nitrate to form nitrogen gas, were discovered in the early 1990s. Here, Gijs Kuenen recalls the discovery of 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 w … The anammox process is catalyzed by anammox bacteria belonging to the phylum of Planctomycetes, which oxidizes ammonium into nitrogen gas with nitrite as electron acceptor in the absence of oxygen The Anammox process was operated as a granular sludge SBR-process. More than 80% of the ammonia was converted into dinitrogen gas at a load of 1.2 kgN/m3 per day.

Kväverening från avloppsvatten är nödvändig för att förhindra övergödning av kust och hav. För att avskilja kväve från avloppsvatten används vanligtvis biologisk rening i två steg: nitrifikation och denitrifikation. The big surprise was the serendipitous discovery of the ‘anammox’‐process, whereby ammonium is anaerobically oxidized to dinitrogen gas with nitrite as electron acceptor. The early days of our anammox research are the main focus of this article, which describes the struggle of growing and identifying the most peculiar bacteria we ever came across. The ANAMMOX® process is a cost-effective and sustainable way of removing ammonium from effluents and ammonia from waste gas.

AOB protect anammox bacteria, which are sensitive to oxygen, during the aerobic cycles of bioreactor opera-tion and supply them with nitrite. The competition for space and nitrite occurs between anammox bacteria, denitrifiers, and nitrite-oxidizing bacteria (NOB) [3]. At the present, the anammox …

Ny SVU-rapport: Användning av Anammox för en förbättrad kväveavskiljning vid avloppsverk (avlopp och miljö) Nyheter • Mar 11, 2016 11:17 CET. Försöken har utförts vid Hammarby som ANAMMOX-bakterien (Amba et al. 2007). Namnet ANAMMOX står för ANaerobic AMMoni-um OXidation och det speciella med bakterien är att den kan rena kväve utan behov av den kolkälla som annars behövs vid normala denitrifikationsprocesser. ANAMMOX-bakterien kallas därför också för ”The Missing Link” i kvävereningsprocessen. Currently, nitritation-anammox (anaerobic ammonium oxidation) bioreactors are designed to treat wastewaters with high ammonium concentrations at mesophilic temperatures (25 to 40°C). The implementation of this technology at ambient temperatures for nitrogen removal from municipal wastewater following carbon removal may lead to more-sustainable technology with energy and cost savings.

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. The anammox cell is divided into three separate compartments by bilayer
