| Research Abstract |
With the ultimate goal of clarifying the algal bloom outbreak mechanism in Lake Hachiro-ko (Akita Prefecture), a novel method was developed for determining quantity of toxic and non-toxic cyanobacteria, by combining competitive PCR with a D NA/RNA analytical microchip electrophoresis device. In addition, the comprehensive genetic diversity analysis of the algal bloom outbreak waters with particular focus attention on eubacteria including cyanobacteria was carried out using a next generation sequencer (NGS). The results confirmed the succession of bacterial populations predicted to contribute to the degradation of sheath (extracellular polysaccharide of cyanobacteria) and the cyanotoxin, microcystin.
