Hiochikin T107 grew in a mixed medium consisting of synthetic medium and dealcoholized sake medium much faster than in either of the component media. The mixing ratio 6 : 4 of the component media seems to be best suited.The growth of Hiochi-kin was much promoted by the supplement of dealcoholized sake, when the syntheric medium was used as the basal medium. Especially sake accelerated the growth in the earlier stages of incubation This activity might be due to the presence on unknown growth factors in sake.We investigated the distribution of these growth factors in several stages of sake-brewing. The samples from rice-koji and moromi-mash (3 days after Tome-zoe) had a considerable activity as compared with the produced sake.The activity of fermentation products of micro-organisms concerned with sake-brewing was investigated. The autolyzates of Asp. oryzae and sake-yeast which were grown in a medium of known composition exerted fairly high activity on the growth of Hiochi-kin.
