摘　　要：微生物发酵可提高玉米蛋白粉饲料的利用率。本研究通过平板培养和发酵试验相结合的方法筛选发酵玉米蛋白粉生产饲料的最佳菌种,并以发酵饲料中的可溶性蛋白含量为指标,利用正交试验确定所用菌种的比例。结果表明:以嗜热乳酸杆菌、枯草芽孢杆菌和热带假丝酵母三种菌株配合发酵效果较好,比例为3∶3∶2时发酵饲料中可溶性蛋白含量最高,为14.47%。The utilization ratio of corn gluten meal feeds can be improved by fermentation.The properstrains used for preparing feeds with corn gluten meal by fermentation were screened by means of platecultivation and fermentation,and the optimal proportion of strains were ascertained by orthogonal experiment.The results showed that the fementation effect was best with the mixed strains of Lactobacillus thermophilus,Bacillus subtilis,Candida tropicalishas.The soluble protein content could be reached14.47%when theLactobacillus thermophilus,Bacillus subtilis and Candida tropicalishas ratio was3:3:2.
