The effects of vitamin B_2-acid (7,8-dimethyl-10-(2,3,4-trihydroxy-4-carboxybutyl)-isoalloxazine) produced by Shizophyllum commune on the growth of Chattonella antiqua were investigated. C. antiqua was cultured in a vessel which was shielded with red cellophane in order to avoid photolysis of flavin.The following results were obtained.1) Vitamin B_2-acid inhibited the growth of C. antiqua while riboflavin, FMN, and FAD did not. One mg/l of vitamin B_2-acid depressed the growth of C. antiqua and 4 mg/l of vitamin B_2-acid killed C. antiqua.2) Cell division of C. antiqua synchronized with the light/dark cycle. When vitamin B_2-acid was added at early in the light period, the inhibition of the growth was shown to be more effective.3) The growth of Skeletonema costatum was not influenced by the addition of vitamin B_2-acid.4) Riboflavin and vitamin B_2-acid inhibited the growth of C. antiqua when the cultivation vessel was not shielded with red cellophane. The effect of vitamin B_2-acid was more powerful than that of riboflavin. The inhibitory effect of vitamin B_2-acid was observed to be most powerful on the day after the addition of vitamin B_2-acid.5) The facts described above suggest that vitamin B_2-acid may be useful for the extermination of C. antiqua from sea water.
