摘　　要：以玉米皮为基本碳源,通过单因素和正交试验,以产朊假丝酵母、啤酒酵母和白地霉联合固态发酵生产蛋白饲料进行了研究。以提高真蛋白含量为主要目的,优化得到最佳的发酵条件为菌液接种量7%,固态发酵培养基料水比1:1.8(g:m L),发酵温度31℃,发酵时间80 h。在此条件下,真蛋白含量可达15.6%,是发酵前的1.94倍。Using corn bran as basic carbon source, protein feed was produced with the solid-state fermentation ofCandicla utili- Saccharomyces cerevisiae and Geotrichum candidum by single-factor and orthogonal experiments. To improve pure protein content, the optimal fermentation conditions were as follows： solid-liquid ratio of solid-state fermentation medium 1：1.8 （g：ml）, inoculum 7%, fermentation temperature 31 ℃ and time 80 h. Under the above conditions, the true protein content in the final product achieved 15.6%, which was 1.94 times of before fermentation.
