摘要: 在全容积１６Ｌ的环隙气升式反应器内，进行了高浓度山梨糖流加发酵过程的研究。根据其发酵过程的特征，建立了流加过程的动力学模型。在此基础上，获得适合该过程的流加控制策略。实验结果表明，采用该控制策略，可使底物浓度的波动范围小于２ｇ／Ｌ。Abstract: Experimental studies were carried out on the fed-batch fermentation process of sorbose in a 16L airlift reactor.According to the characteristics of the fermentation process, a kinetic model of fed-batch fermentation was established.On the basis of the kinetic model, a control strategy which was used to control fed-batch fermentatin process of sorbose was obtained.The experiments showed that using the control strategy,the fluctuation range of substrate concentration is less than 2 g/L.
