MEDIUM FOR CULTURING ALGAE AND MANUFACTURING METHOD FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a nourishment medium for culturing algae capable of supplying nutrition according to the growth of the algae by floating on the sea water and functioning as the nucleus of the proliferation in a large scaled culturing of algae in the ocean which is needed for fixing atmospheric CO2 by culturing algae. SOLUTION: The algae culturing medium is comprising inorganic materials such as coal ash or the like, a hardening agent, a nutrition component for algae culturing and weight saving materials, and the raw materials are formed into the algae culturing medium having less than 1 g/cm<3> of density, the obtained medium is scattered to the sea water and let to float. This nourishment medium for culturing algae functions as the nucleus of the proliferation of the algae and the nourishment of the algae is gradually supplied according to the proliferation of the algae allowing the proliferation of the algae in the boundless ocean.
