Using submersibles, the Japan Agency for Marine-Earth Science and Technology Institution has found new species of deep-sea multicellular organisms with a high frequency. The novel substances isolated from such newly discovered organisms are expected to be valuable in pharmaceutical, cosmetic, food and industrial applications. However, the problem is that the number of the deep-sea organisms that can be captured using submersibles is very limited. We, therefore, made a new attempt to convert the rare deep-sea organisms into "bioresources that can be amplified." We successfully established the genomic libraries from 34 species of the deep-sea organisms and the cell libraries from four species.
