搅拌对红霉素发酵的影响

在20t工业发酵罐中，研究了涡轮桨和翼形轴流桨搅拌对红霉素发酵过程的影响，重点考察了粘度、溶氧、效价、搅拌电流和糖代谢等过程参数的变化，以及搅拌功耗与发酵产量之间的关系。研究结果表明：(1)不同的搅拌桨搅拌其发酵过程参数(粘度，溶氧，效价等)随时间的变化曲线有明显的差异；(2)搅拌功耗同发酵产量之间的关系，翼形桨明显不同于涡轮桨；(3)在相同的生产条件下，用翼形桨代替涡轮桨可节省搅拌功耗。

The Effects of Agitation on Erythromycin Fermentation

The effects of agitator type on erythromycin fermentation, and variation of fermentation parameter such as broth viscosity,dissolve oxygen,fermentation unit,power consumption, etc with time were studied. The results showed that process parameters varied with time in fermentation is distinct for different agitator, the hydrofoil impeller replace the disc turbine impeller, might significantly reduce power consumption at the same.
