| Outline of Final Research Achievements |
Biological nitrification/denitrification process has been a standard method to remove nitrogen in waste water. The process, however, has expended considerably investment in equipment and the running cost because the process requires anoxic conditions for facultative heterotrophic bacteria. This study aimed to establish the alternative method to the conventionally-biological process. This study used Chlorella-like symbiotic algae isolated from Paramecium bursaria for removal of ammonia nitrogen. After treatment of algae encased in an alginate capsule with ammonia, the algal capsules could remove ammonia significantly. Although these algae have a unique characteristic to release photosynthetic products, these algal capsules could also release them. Furthermore, this study investigated metabolic changes of algae after treatment with ammonia using GC-MS spectrometry. Results showed that amounts of several organic components in algae changed between control and the test condition.
