摘  要:
利用计算流体力(CFD)模拟软件对地衣芽孢杆菌摇床培养过程中的内部流场进行预测。为准确模拟摇床内部速度场和温度场在摇床振荡过程中的变化,对整体摇床进行网格加密处理。采用CFD模拟结合接种实验,重点考察了不同摇床位置对地衣芽孢杆菌生产聚谷氨酸的产量影响,同时研究由位置不同引起产量不同的机理。通过模拟结果和实验结果的相关性比对,得出下层摇床的内侧区域最适宜地衣芽孢杆菌生长。

摘  要:
The flowing field by Bacillus licheniformis in shaker had been simulated with the CFD software(fluent).The relationship between the γ-PGA production and the flask position at the shaker was studied.Finally,the optimum position was determined and located lower level,inner side.
