三、A.菌株的适宜培养条件1.培养基:斜面用马铃薯蔗糖琼脂效果较好,32℃培养24小时就可长成丰满菌苔。液体扩大培养以糠饼粉培养液为最好(表2),其培养物含菌量达0.87×10~8个/ml,脱胶效果为3.1~+。固体扩大培养以第3号配方最好(表3),其培养物含菌量达7.9×10~8个/克,且其培养物及浸出液脱胶效果均达到大部分脱胶。第5号培养基培养效果亦较好,但原料成本较高,不利于在生产上应用。2.温度:试验结果表明,在34—38℃的 Third, A. suitable strains of culture conditions 1. Medium: bevel potato sucrose agar better, 32 ℃ cultured for 24 hours can grow into full lawn. Liquid expansion culture was best with bran powder culture medium (Table 2). The culture medium contained 0.87 × 10-8 cells / ml and the degumming effect was 3.1 ~ +. The best solid No. 3 formula was obtained (Table 3). The culture medium contained 7.9 × 10-8 cells / g, and the degumming effect of culture and leachate reached most of the degumming. No. 5 culture medium is also better, but the higher cost of raw materials is not conducive to the application of production. 2. Temperature: Test results show that at 34-38 ℃
