  cell growth
     The parameters of the kinetic models were established with experimental data. The models for cell growth, elastase formation and glucose consumption model were described by the following equations:dx/dt=0.180(1-x/9.77)x,dp/dt=-dx/dt=4.278x and -ds/dt=0.03(dx/dt)-7.53x, respectively.
     根据实验数据确定了模型参数,得到菌体生长动力学模型为dx/dt=0.180(1-x/9.77)x,弹性蛋白酶生产动力学模型为dp/dt=-dx/dt=4.278x以及葡萄糖消耗动力学模型-ds/dt=0.03(dx/dt)-7.53x。
