| Outline of Final Research Achievements |
In this study, we aimed to study microorganisms inhabiting subseafloor biosphere, which is one of the largest microbial biosphere on the Earth. Through developments of techniques to detect, separate, and selectively separate (sort) microbial cells with cleanest possible handling environment, we successfully detected very low biomass in the sediment and probe its metabolic activity through NanoSIMS (Nano-scale Secondary Ion Mass Spectroscopy) analysis.
