| Research Abstract |
To clarify bacterial diversity in the geological static deep-sea sediment, I tried to extract RNA to make cDNA libraries. The Automatic Bottom Inspection and Sampling Mobile "ABISMO" succeeded sampling at the deepest Mariana Trench, however, the included microbe was lower amount than previous report. Then, preliminary experiment was performed using the sediment in the static Izu-Ogasawara Trench. The population of Chloroflexi surrounding giant protist was significantly lower than the plain sediment, suggesting that bacteria in the activity state were distributed heterogeneously in the geologically static environment by coexistence with the large-sized creature.
