- Abstract:
- Heterotrophic nitrification-aerobic denitrification (HNAD) bacteria have drawn more and more attention as possessing the advantages that autotrophic nitrifying organisms (ANOs) and ordinary heterotrophic organisms (OHOs) do not have, such as, conducting the nitrification and denitrification processes simultaneously, and fulfilling the biological denitrification process under completely aerobic conditions. The distribution of HNAD bacteria, the factors affecting the denitrification performance, related enzymes and functional genes, and denitrification pathways were summarized. In addition, the differences among the HNAD, ANOs and OHOs bacteria were also discussed. Eventually, the future development of the HNAD was prospected.
