【摘要】 采用密闭通风发酵设备对苏芸金杆菌ＢＴ—３７进行了中试规模液体深层发酵的实验和生产，就不同黄豆饼粉含量培养基和不同种子罐培养菌龄对最终发酵液活菌含量的影响作了初步探讨，为进一步优化工艺控制打下了基础。更多还原

【Abstract】 The effects of bacteria age in seed tank and soybean powder content in culture on upto-scale fermentation of Bacillus thuringiensis are tested with the strain of BT-37. The results indicate that the tenth hour is the best moment for seed bacteria transformation,and 5. 5% soybean powder culture has the maximum yield in final fermentation liquid.These works do the basic researches for further studies on optimigation of technological control of B. thuringiensis fermentation.更多还原
