Hiochi-kin T101,T102,T105,and T107 grew in synthetic non-alcohol media, utilizing exogenous supply of purines. Each of adenine, guanine, xanthine, xanthine, hypoxanthine stimulated the growth of Hiochi-kin equally in the presence of essential folic acid. Strains T101 and T102 required purines essentially, but the other strains were only stimulated by them. Supplement of mxture of 4 purines was the best source for the maximum growth. Pyrimidines had no effect on the growth of Hiochi-kin. Also vitamin B_<12≷ and thymidine were found to be non-effective on the utilization of purines. When folic acid was omitted, thymine plus purines stimulated T105 and T107 moderately.Ethanol is an important factor for the growth of Hiochi-kin, because the bacteria muitiply in Japanese Sake which contains plenty of ehanol. The effect of ethanol was investigated on the utilization of purines. In 10 vol% ethanol high concentration of purine (2×10^<-4>M) reduced the growth as compared with lower concentration.
