| Outline of Final Research Achievements |
The same uncultured clone was detected in clone analysis targeting nirS and aprA gene in tidal flat sediment sampled from Midorikawa, Shirakawa, and Yatsushiro sea. To clarify the characteristics of the uncultured clone, enrichment culture and isolation were corried out from the tidal flat sediments. Especially in sulfur oxidizing bacteria, which are important for sulfur cycle in tidal flat, both of heterotrophic and autotrophic bacteria were obtained. Therefore, not single group like sulfate reducing bacteria but multiple number of various sulfur oxidizing bacteria construct the oxidation reaction cycle.
