摘　　要：以马铃薯淀粉生产中产生的废渣为主要原料,以黑曲霉、白地霉和热带假丝酵母为发酵菌种,优化了马铃薯薯渣固态发酵生产菌体蛋白饲料的发酵工艺,初步确定了薯渣固态发酵的适宜条件,即采用自然pH值,物料质量比(薯渣:麸皮)为90:10(w/w),发酵温度32℃,发酵时间66h,在此条件下发酵饲料中粗蛋白含量较高。Using potato residue from potato starch production as main material, the solid-fermentation of bacterial protein feeds by Aspergillus niger 2103, Geotrichum candidum 31348 and Candida tropicalis 1254 was optimized. The results indicated that the optimum conditions of fermentation were as follows： natural pH, the proportion of potato residue to bran was 90：10 （w/w）, fermentation temperature 32℃ and fermentation time 66 h. Under above conditions, the crude protein content of feeds was higher.
