摘要
在1,3-丙二醇有氧分批发酵中,研究了Klebsiella pneumoniae的生长、底物甘油消耗及1,3-丙二醇的产生特性。基于Logistic方程和Luedeking-Piret方程,得到了描述1,3-丙二醇有氧分批发酵过程的动力学模型及模型参数,该组模型能很好的拟合发酵过程,并在初始甘油浓度变化较大的范围内表现出很好的适用性。同时所建立的模型也基本反映了Klebsiella pneumoniae分批发酵过程的动力学特征。
The aerobic fermentation process of 1,3-propanediol by Klebsiella pneumoniae with glycerol as substrate was studied in batch system.A kinetic model was proposed based on the Logistic and Luedeking-Piret equations of cell growth,product formation and substrate consumption.With the evaluated model parameters,the model appears to be providing a reasonable description for the fermentation process under various conditions.
