The discharge of organic and inorganic nitrogenous pollutants in wastewater leads to eutrophication disrupts the ecological balance. Therefore, pressing need for an effective treatment method has become increasingly evident. A robust bacterium Pseudomonas stutzeri H3 capable simultaneous nitrogen removal was isolated from activated sludge coking system. optimal conditions ammonium quinoline were as follows: C/N ratio 15–20, initial pH 7–8, culture temperature 30 °C, shaking speed 150–300 rpm. At 200 mg/L 100 quinoline, strain achieved above 90% efficiency, exhibiting excellent capabilities. outstanding efficiencies presence different sources further confirmed capability H3. whole genome sequencing metabolic intermediates determination performed elucidate gene function annotations, genes, pathways. findings provide a promising pathway treat wastewater.

Immobilization Technology of Aerobic Denitrifying Bacteria and Its Enhanced Biological Denitrification: A Review of Recent Advances

Water, Год журнала: 2025, Номер 17(10), С. 1433 - 1433

Опубликована: Май 9, 2025

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.
