| Outline of Final Research Achievements |
This study revealed the relationship between the clades of polyphosphate accumulating bacteria (PAOs), which are rich in diversity depending on salinity, and favorable environment conditions of the respective clades. The diverse PAOs were successfully cultivated by a DHS reactor under different salinity conditions, suggesting that it is possible to recover polyphosphate as concentrated solution from not only wastewaters but also seawater and brackish water.
