菜籽饼粕粗蛋白降解菌的筛选、初步鉴定与发酵条件摸索

Screening、Identification and Fermentation Conditions of The Crude Protein-Degradative Strain

在接种了诱变菌株A的未灭菌的菜籽饼粕发酵样品中筛选得到3株能以菜籽饼粕为原料生长的菌株,编号为S1、 S2、S3,3株菌种通过鉴定确定为圆孢芽孢杆菌、短小芽孢杆菌和球形芽孢杆菌。通过设计正交实验摸索出这3株菌种和诱变 菌株A的最佳培养条件。对饼粕固体混合菌发酵进行了初步摸索和探讨。

Three strains have been isolated from the rape cake samples. By orthogonal experiments, the optimum conditions of cultivation were determined.
