Outline of Final Research Achievements

The anaerobic ammonia-oxidizing (anammox) process has high potential as a biological nitrogen removal wastewater treatment process. In recent years, practical use of the anammox process has increased in wastewater treatment plants and chemical factories. However, there are many parts that still remain unknown in their microbial ecology and physiology. In this study, metagenomic analysis was conducted to understand the impact that operation conditions have on the bacterial community. In the pretreatment process, no difference in the microbial community was observed between the steady state and suspended conditions, whereas in the nitritation process and anammox process, the difference in the microbial community was confirmed.
