摘 要:本研究在摇瓶水平上优化了多黏芽孢杆菌(Bacillus polymyxa)的发酵培养基,以提高多黏菌素B的产量。采用单因素试验法和响应面法优化发酵培养基配方,并在7 L发酵罐中进行验证。优化后的发酵培养基配方为全麦粉6.7%、玉米浆粉0.3%、葡萄糖0.5%、硫酸铵0.9%、磷酸二氢钾0.03%和碳酸钙0.03%。此条件下,多黏菌素B的摇瓶发酵产量为0.95 g/L,较优化前提高120.9%,7 L发酵罐中的产量为1.06 g/L。A single factor experiment and response surface methodology were employed for the optimization of culture medium for polymyxin B production from Bacillus polymyxa.The optimum culture medium was verified on the 7 L fermentation tank as follows:wheat flour of 6.7 %,corn steep powder of 0.3 %,glucose of 0.48 %,ammonium sulfate of 0.9%,monopotassium phosphate of 0.03% and calcium carbonate of 0.03 %.Under such conditions,the yield of polymyxin B was 0.95 g/L in shaking flasks,120.9% higher than the original,and it was 1.06 g/L in the 7 L fermentation tank.
