摘　　要：以固态发酵培养方式 ,通过正交试验对黑曲霉和饲料酵母在秸秆上共发酵生产单细胞蛋白的条件进行了研究。其最佳条件为 :酵母种类为产朊假丝酵母 ,接种间隔时间为 2 0h ,接种量为 10 %。培养后蛋白含量可达到49% ,且含有多种酶和氨基酸。不同预处理对发酵结果的影响也作了一定的研究 。Optimal co-fermentation condition for single cell protein with Aspergillus niger and feed-yeast by orthogonal and experiment were developed. The optimal conditon was the feed-yeast of candida tropocalis was added 20 hours later than the Aspergillus niger, and the incoculum volume was 10%. The protein yield was up to 49% after fermentation, the protein contained various enzymes and amino acids.
