摘　　要：研究了以红麻亚铵法制浆废液为原料生产饲料酵母的可行性。研究发现,红麻亚铵法制浆废液有利于白地霉AS2.1035的生长。优化条件为:废液浓度7°Be′、pH值6.0、发酵温度27℃、摇瓶发酵时间54h、磷酸氢二钾用量2.0g/L、摇床转速140r/min、摇瓶装液量50mL、ZnSO4用量1.0g/L,在此条件下可以得到较好的发酵效果,菌体质量浓度达到8.332g/L,CODCr去除率达到58.7%,饲料酵母中所含蛋白质为38.2%,含铅、铬和镉量符合饲料卫生标准。The feed yeast was produced by the ferment Geotrichum candidum AS 2. 1035 in kenaf ammonium sulfite pulping waste liquor. The results indicated that the kenaf ammonium sulfite pulping waste liquor is suitable for the growth the Geotrichum candidum AS2. 1035. The optimal conditions are as follows ： the consistency of waste liquor 7′Be, pH value 6. 0, temperature 27℃, time 54h, the rotating speed 140rpm, the liquor amount of the shaking bottle 50mL, dosages of K2HPO4 and ZnSO4 · 8H2O are 2. 0 g/L and 1.0 g/L respectively. Under the conditions, the production of Candida tropicalis is very well, the production is 8. 332 g/L, the removal rates of CODcr is 58.7% ; the content of protein is 38.2% in the microorganism feed, and the content of Pb, Cr, Cd is satisfied with the requirment of the standard of feed sanitation.
