| Outline of Final Research Achievements |
The objectives of this study were (i) to develop the super-symbiotic plant and microorganisms association for wastewater treatment, (ii) to clarify the mechanisms of the symbiotic association and (iii) to demonstrate high-efficient wastewater treatment by using the super-symbiotic association. First, plant growth promoting bacteria (PGPB) of duckweed and common reed were isolated. The PGPB could promote growth, biomass production, photosynthesis and nitrogen uptake of duckweed/common reed. I demonstrated the accelerated nitrogen removal from wastewater by using the symbiotic association. Second, endocrine-disrupting chemicals (EDCs)-degrading bacteria were isolated and characterized. Duckweed and common reed could promote degrading activity/growth activity of the EDC-degrading bacteria. I constructed the symbiotic plant and EDC-degrading bacteria association, and demonstrated the efficient and sustainable removal of EDCs from contaminated wastewaters by using the association.
