| Research Abstract |
In the present study, we revealed enzymatic pathway of microbial microcystin degradation in microcystin-degrading bacterium. The abundance of mlrA gene in aquatic environment strongly related to microcystin concentration, thus microcystin-degrading bacteria play a key role in microcystin degradation. Moreover, we confirmed that Adda induce expression of mlrA and mlrB, and cyclic structure of microcystin relate to expression of mlrC. Finally, we have constructed new water treatment apparatus using electrochemical degradation without electrolyte. The apparatus inhibit toxic cyanobacteria growth, but do not inhibit other organism, such as animal plankton and fish.
