摘要
微生物培养是生化工程中的一个重要课题。研究了一个非线性连续微生物培养动力系统的极限环的相对位置。对带非常数产物系数的连续培养模型进行推广。模型中的极限环对应于发酵和生化培养中的非线性振荡,其相对位置对研究连续培养中振荡产生的时间和范围是有意义的。
The microbial growth is an important topic in biochemical engineering. In this paper, we study the limit cycles in a nonlinear deterministic model in the continuous culture vessel with variable yield, the location of limit cycles is estimated. The model is a generalization of the one proposed by the model of non-constant yield coefficient. Since the limit cycle is corresponding to the nonlinear oscillation in the continuous culture vessel, the location of limit cycles is very useful in the further study of the oscillatory behaviors of the microbial growth in the vessel.
