Engineering doi: 10.1016/j.eng.2023.09.013

Abstract: The availability of nitrogen (N) is crucial for both the productivity of terrestrial and aquatic ecosystemsHowever, the overuse of artificial fertilizers and the energy required to fix nitrogen have pushed theglobal nitrogen cycle (N-cycle) past its safe operating limits, leading to severe nitrogen pollutionThe anaerobic ammonium oxidation (anammox) mechanism can counteract the release of ammonium and N2O inBased on the discovery of an anammox hotspot capable of oxidizing ammonium anoxically into N2 without
