| Outline of Final Research Achievements |
Promotion of issues regarding technology development for a sustainable supply of water is important. One pressing issue is the control of microorganisms in activated sludge which is required in waste water treatment. Microorganisms exist as multi-species biofilms, however, biofilm control is often based on engineering approaches, such as nutrients, pH, and oxygen supply, but these approaches are rapidly reaching their limit. Therefore, control technology and the theory of innovative multi-species biofilms is of vital importance. In light of this, we investigated cell-cell communications in activated sludge, and indicated that interactions between bacteria exist in activated sludge by using a new imaging technology.
