摘　　要：以棉仁饼为原料，热带假丝酵母ＺＡＵ－１为菌种，采用固体发酵技术，对无游离棉酚的酵母饲料进行了研究，探讨了不同原料对酵母饲料发酵的影响，筛选出较合理的固体发酵培养基：棉仁饼６０％，大米蛋白粉２５％，麸皮１０％，饴糖２％，酒糟１％，ＭｇＳＯ４５Ｈ２Ｏ０．２５％，ＫＨ２ＰＯ４０．７５％，ＦｅＳＯ４７Ｈ２Ｏ０．８０％，ＺｎＳＯ４７Ｈ２Ｏ０．２０％，ＭｎＳＯ４Ｈ２Ｏ０．０６％，ＣｕＳＯ４５Ｈ２Ｏ０．０４％和ＣｏＣｌ２６Ｈ２Ｏ０．０２％．The yeast feed of cotton seed cake fermented by Candida tropicalis ZAU 1 with solid state was studied, and the effect of various ingredient on yeast feed fermentation was described The optimum fermentation medium was obtained which included cotton seed cake 60%, rice protein meal 25%, wheat bran 10%, molasses 2%, winelees 1%, MgSO 4·5H 2O 0 25%, KH 2PO 4 0 75%, FeSO 4 ·7H 2O 0 80%, ZnSO 4·7H 2O 0 20%, MnSO 4·H 2O 0 06%, CuSO 4·5H 2O 0 04% and CoCl 2·6H 2O 0 02%
