The Japanese are unparalleled as a nation fond of eating fishes and seaweeds. Generally speaki-ng, sea-weeds are indigestible, and their carbohydrate is less digestible than that contained in other foods. Therefore, in utilizing sea-weeds, it is necessary that attention should be paid to that point, and steps taken to correct it and fully utilize the nutrition value of sea-weeds. Sea-weeds, when used as a fertilizer, should be decomposed in advance to make their abs-orption by crops easy. For the above purpose, we made this experiment by isolating a certain specific bacillus and inoculating it to sea-weeds. This bacillus is similar to Bacillus subtilis, and in this experiment we used Eisenia bicyclis (Kjellm), Ecklonia cova kjellm, and Laminaria japonica Aresch among phaoephyceae In summer they were left alone at a room temperature of 27-31°C, and in other seasons in an incubator (25°C).Their decomposition was recognized in 5-20days. Decomposition of Laminaria was found to be somewhat inferior to other sea-weeds. Change in chemical composition and methods of utilization of sea-weeds shall be mentioned in our second report.
