Abstract Complete ammonia oxidizing bacteria, or comammox bacteria (CAOB), can oxidize ammonium to nitrate on its own. Its discovery revolutionized our understanding of biological nitrification, and distribution in both natural artificial systems has enabled a reevaluation the relative contribution microorganisms nitrogen cycle. wide distribution, adaptation oligotrophic medium, diverse metabolic pathways, means extensive research CAOB application water treatment be promoted. Furthermore, energy-saving characteristics high oxygen affinity low sludge production may also become frontier directions for wastewater treatment. This paper provides an overview environmental CAOB, as well physiological microorganisms, such nutrient factors, enzymes, metabolism, focusing future Further should carried out analyze ecological niche impact explore potential cycle improvement.

Simultaneous nitrification and denitrification (SND) is effective energy-saving for wastewater treatment. As an inevitable intermediate product in the SND process, nitrite affects efficiency of ammonia oxidation composition nitrifiers. To investigate impact on efficiency, two reactors performing were respectively operated without (R1 as control) with 20 mg N/L addition (R2 experimental). The total nitrogen removal was 74.5% R1 while 99.0% R2. With (i.e., N/L), rate R2 increased to 4.5 times that R1. ammonia-oxidizing archaea (AOA) bacteria (AOB) contributed respective around 46.9% 41.8% based results experiments specific inhibitors. number AOA AOB monooxygenase gene (amoA) copies by 280 30 due addition, according qPCR results. high-throughput sequencing illustrated increase dominant species from 0.40% 1.59% phylogenetic tree analysis revealed a close link Nitrosospira multiformis. These indicated improved AOA/AOB enriched addition. reductases boosted adaptation This study demonstrated positive impacts process.
