The rising urbanization and industrialization are increasing nitrogen pollution in water wastewaters, calling for advanced remediation treatments. Traditional biological treatments limited area efficiency. Therefore, heterotrophic nitrification-aerobic denitrification (HN-AD) a single reactor has drawn significant attention shown higher Here we review HN-AD bacteria with focus on bacterial species, metabolism, factors influencing denitrification. Nitrogen metabolism pathway includes nitrate-nitrite reduction denitrification, hydroxylamine assimilatory Factors comprise carbon source, C/N, temperature, pH, DO so on. Compared to published literature reviews HN-AD, our manuscript comprehensively summary the latest research its remove mechanisms related enzymes first time.

ABSTRACT The growth and nitrogen metabolism of heterotrophic nitrification‐aerobic denitrification (HN‐AD) bacteria are affected by nitrite, but the mechanisms underlying this for strain Acinetobacter johnsonii EN‐J1 unclear. In study, addition 10 mg/L nitrite increased reduction rate ammonium 1.0 mg/L/h, 20 nitrate 3.9 mg/L/h. Compared with control, reductase activity, electron transfer adenosine triphosphate content were enhanced 142.0%, 278.0% 279.0%, respectively, in removal process after nitrite. whole genome was annotated genes such as narGHI , narK nsrR nirBD nasA glnA gltB gdhA amt . Transcriptome analysis showed that triggered significant upregulation several key pathways, including metabolism, tricarboxylic acid cycle, amino enhancing denitrification. expression ( narG hmp ) detected real‐time quantitative polymerase chain reaction. These results suggested enhances increasing genes, levels, which is important elucidating mechanism promotion biological efficiency.
