摘要
在分批发酵中研究了分枝杆菌(Mycobacterium sp-UV-8)的菌体生长、基质消耗及产物生成的特征,基于Logistic方程和Leudeking-piret方程建立了描述分批发酵过程的动力学模型及模型参数,并对试验数据与模型进行验证比较,结果平均相对误差均小于7%,模型计算值与试验数据拟合良好,基本反映了Mycobacterium sp-UV-8分批发酵过程的动力学特征,表现出很好的适用性,为产业化设计和生产提供了可靠的保障。
The fermentation process of Mycobacterium sp-UV-8 was studied in batch system, and a kinetic model was proposed based on the Logistic and Leudeking-piret equations for microorganism growth, product formation and substrate consumption. Depending on the evaluated model parameters, the model appears to provide a reasonable description for the fermentation process,and the average relative error was no more than 7%. The calculated results of models were compared satisfactorily with experimental data, which offers assurance for the industrial design and production throught degradation of phytosterol by Mycobacterium sp-UV-8.
