1) In the ethanol-containing synthetic media supplemented with extracts of various natural materials the yeast No. 110 was cultivated under static condition. As the result, the effects of the extracts of radish leaves, rice bran, bagasse, sweet potato and pepper leaves upon the growth acceleration of the yeast were great.2) The yeast No. 110 assimilated ethanol pretty well in the media containing only ethanol and salts, but the rate of ethanol assimilation was inferior to that of Torulautilis. The effects of the added substances on the growth of the yeast in the basal media were remarkable except the basel medium B.3) Generally, Torula utilis assimilated ethanol well in the media containing only ethanol and salts, especially in the basel medium B it grew luxiantly and the yield of the yeast was 56% on the basis of the added ethanol In this basal medium the added substances produced no remarkable effect on the growth of the yeast.4) The high yields of both the yeasts from the media used are shown in Table 11. Generally, the effects of the extracts of radish leaves and rice bran, peptone and asparagine on the growth acceleration of both the yeasts in the basal media were great, except the basal medium B,
