| Research Abstract |
The goal of this study is construction of a platform towards the practical application of phages for water management thorough understanding relationships between toxic cyanobacteria, Microcystis and its infectious cyanophages. The main results can be summarized as follows; A Microcystsbloom consists of multiple genotypes each of which has been continuously attacked by diverse communities of phages. The genotypic composition of Microcystis fluctuates over time but the genotypic diversity has been maintained. Increased contact frequency of a Microcystis-phage population promoted genetic diversification.
