| Outline of Final Research Achievements |
In the brackish Lakes Shinji and Nakaumi, picocyanobacteria (cells ca. 1 μm in diameter) have been frequently dominant, but species were not confirmed and the roles in the ecosystem were not known. Pycocyanobacteria strains (ESS-1-2 and S3-1) were identified as Cyanobium sp. by the observation of cell morphology and the molecular analysis. Culture conditions of ESS-1-2 and several phytoplankton of Lake Shinji were established for the feeding experiment of Corbicula japonica. We observed a process of the digestion from feces and gastrointestinal observations of Corbicula japonica with ESS-1-2. After checking the effectiveness as the bait of Corbicula japonica with ESS-1-2, a diatom and a green alga, a diatom was the most effective as bait.
