通过保持乙醇浓度恒定，开发了面包酵母补料分批培养中葡萄糖补料速率的反馈控制系统。采用多孔聚四氟乙烯管法，对PID控制器和开关控制器进行了应用和讨论。实验结果表明，该控制系统能够有效地避免葡萄糖效应和葡萄糖饥饿。结果表明，在补料分批培养中，所开发的反馈控制系统可以实现0.3 h-1的最大比生长速率或0.5 g细胞/g葡萄糖的最大细胞产率。
A feedback control system of the glucose feed rate in a bakers' yeast fed‐batch culture was developed by keeping the ethanol concentration constant. A PID controller and on–off controller were applied and discussed with the aid of the porous Teflon tubing method. Experimental results showed the effectiveness of the control system for avoiding the glucose effect and glucose starvation. It was shown that the feedback control system developed hare could achieve a maximum specific growth rate of 0.3 h−1 or a maximum cell yield of 0.5 g cell/g glucose in the fedhyphen;batch culture.
