摘要
利用对黑曲霉、白地霉、热带假丝酵母、产朊假丝酵母及添加纤维素酶混合发酵啤酒糟生产饲料蛋白质进行了初步的研究.正交试验结果表明，最佳原料配比为 m(啤酒糟 )∶ m(麸皮 )∶ m(豆粕 )=80∶ 15∶ 10，原料含水量为 60％，其最佳发酵条件为发酵温度 30℃ ,pH为 6.0,接种量为 2％，培养时间 3 d. 成分分析结果表明，发酵产物营养丰富，粗蛋白含量达 41.52％.
The cultural conditions of fermentation brewer's grains to produce feeding proteins using Asp. niger， G.candidum,C.tropicalis， Candidauilis and cellulase were reported by means of orthogonalizing process .The optimal culture conditions were : brewer's grain∶ wheat bran∶ bean cake=80∶ 15∶ 10, water content 60％ ,pH6.0,inoculatian size 2％ , culture temperature 30℃ for 72 h. The analysis of the fermented products showed that content of crude proteins of the fermented products reached 41.52％ .
