摘　　要：以α-蒎烯生产菌株YJM28为供试菌株,对其发酵动力学特征进行了研究。通过对Logistic等方程进行了最优参数估计和非线性拟合,得出了α-蒎烯的发酵动力学模型及相关参数。并且对动力学模型的拟合曲线分析可知,发酵实验值与模型预测值能够较好的吻合,说明所建立的发酵动力学模型能够较好的反应α-蒎烯的发酵过程。The dynamic models for alpha-pinene fermentation by Escherichia cold were studied. The kinetic models for cell growth,aipha-pinene production and substrate consumption were proposed with Logistic equation, Luedeking-Piret equation and Luedeking-Piret-Like equation though the optimal parameters estimation and nonlinear least-squares fitting method. The observed and estimated values of the models were in a good agreement,the result showed that the models could provide a reasonable description for the fermentation process of alpha-pinene.
