Anammox, an abbreviation for ANaerobic AMMonium OXidation, is a globally important microbial process of the nitrogen cycle. The bacteria mediating this process were identified in 1999, and at the time were a great surprise for the scientific community. It takes place in many natural environments and anammox is also the trademarked name for the anammox-based ammonium removal technology that was developed by the Delft University of Technology.
