Cooperation between anammox bacteria and other functional bacteria in wastewater treatment: a mini-review

ABSTRACT

Anaerobic ammonia oxidation (anammox) process is regarded as an efficient and cost-effective technology for nitrogen removal. Anammox bacteria typically coexist with other microorganisms, which highlights the necessity to optimize the system, improve the pollutant removal efficiency and maintain the system stability. This review mainly focused on the interaction effects of anammox bacteria with other functional bacteria, such as aerobic ammonia-oxidizing bacteria, sulphur-oxidizing bacteria, sulphate-reducing ammonia oxidation bacteria, denitrifying bacteria, denitrifying anaerobic methane oxidation microorganisms, denitrifying phosphate-accumulating organisms. This review provided support for the emerging insights that the synergistic effects of various functional bacteria related to nitrogen, phosphorus, sulphur, and carbon within the anammox system could be a promising direction for the development of wastewater treatment technologies. By considering the interplay and cooperation of these microorganisms, wastewater treatment systems could potentially achieve more comprehensive and efficient removal of multiple pollutants. Continued in-depth research and understanding of these interactions would be instrumental in exploring innovative and integrated solutions, ultimately aiming for a more effective and holistic approach to wastewater treatment.
