Aerobic denitrifying microorganisms, with their strong environmental adaptability, low dissolved oxygen concentration requirements, rapid growth rate, and high nitrogen removal efficiency, significantly compensate for the shortcomings of traditional aerobic chemolithoautotrophic nitrification anaerobic heterotrophic denitrification models. The introduction denitrifiers can effectively enhance nitrate nitrogen. However, directly inoculating into wastewater leads to issues such as easy loss bacterial cells difficulty in forming a dominant flora, thus preventing long-term maintenance enhancing effect on performance. To address this problem, microbial immobilization technology has been introduced remediation process nitrogen-polluted water bodies. This maintain biomass concentration, provide stable breeding ground prevent microorganisms. article systematically reviews current status isolation bacteria, key enzymes, genes, well application progress bacteria technology, aiming solid theoretical support practical promote its further development field pollution control.
