In the crude alcohol-containing synthetic media supplemented with extracts of some natural materials, peptone and asparagine, five kinds of yeasts i.e., Torula utilis, yeast No. 110,Mycotorula japonica, Rasse XII and FLEISCHMANN's yeast were cultivated under shaking. The results obtained were as follows : 1) Torula utlils, ysast No. 110 and Mycotorula japonica grew pretty well in the media containing only crude alcohol and salts, but Rasse XII and FLEISCHMANN's yeast made a poor growth.2) Generally, the effects of added substances upon the growth of these yeasts were great in the cultures supplied with the crude alcohol in a large amount, and the extract of radish leaves accelerated the growth of Mycotorula japonica, Rasse XII and FLEISHCHMAN's yeast remarkably.3) Relation between the amount of the crude alcohol added and the yield of yeast varied remarkably with the kind of yeast. The yield of Torula utilis increased with the amount of the crude alcohol added, but the growth of Rasse XII and FLEISCHMANN's yeast was inhibited remarkably by the addition of a large amount of the crude alcohol to the culture media, so that the yields of these yeasts from the media were very low.4) Generally, the yields of the five kinds of yeasts from an equal amount of the crude alcohol increased as much as its concentration in the medium decreased.5) The high yields of the five kinds of yeasts obtained from the media used are shown in Table 7.In the media containing a small amount of the crude alcohol, each yeast grew pretty well by the addition of various substances, and more than 20 g of dried yeasts were obtained on the basis of 100cc of the crude alcohol.
