摘要
文章对Plectania YM421黑色素产生的分批发酵过程和发酵动力学进行了研究;应用Logistic方程和Luedking-Piret方程,得到了描述Plectania YM421菌体生长、黑色素产生和底物消耗的动力学模型;模型反映了该菌株产生黑色素分批发酵过程的动力学特征,模型值与实验值数据拟合性较好,该动力学模型对指导Plectania YM421黑色素的发酵生产具有实际意义。
In this paper, the melanin produced by the batch fermentation of Plectania YM421 and fermentation kinetics are studied. The kinetic model is built to describe the cell growth, melanin production and substrate consumption based on Logistic equation and Luedeking-Piret equation. The model shows kinetic properties in the production process of melanin by batch fermentation. The calculated results of model fits well with the experimental data. The kinetic model is of practical significance to guide the melanin production by the fermentation of Plectania YM421.
