| 摘 要： | 以麦角固醇质量分数达３％以上的酵母菌株Ｙｓ－５和Ｙｓ－１６为培养菌，进行了用啤酒糟酶解液代替糖蜜培养基发酵生产麦角固醇的实验．结果表明，在最适条件下，添加少量自溶性酵母，酵母菌的麦角固醇产率可提高２０％左右．

STUDY ON ERGOSTEROL PRODUCTION FROM YEAST CULTIVATED WITH ENZYMOLYSIS FLUID OF BREWER'S GRAINS |
| |
| Abstract: | The enzymolysis fluid of brewer's grains was substituted for the molasses medium to cultivate yeast strains Ys-5 and Ys-16 with the ergosterol mass fraction up to 3%. The result showed that under the optimum conditions and by adding a small amount of autolytic yeast, the ergosterol content of the yeast could be increased by about 20 %. |
