摘要
在5L发酵罐试验数据基础上,对植物乳杆菌合成共轭亚油酸(CLA)的分批发酵动力学特性进行研究,通过Lo-gistic方程提出发酵过程中菌体生长、CLA合成、基质消耗的动力学模型。采用Origin6.1软件对试验数据进行处理,得到植物乳杆菌合成CLA分批发酵的动力学模型参数。结果表明:模型与试验数据能较好地拟合,基本上反映了植物乳杆菌合成CLA分批发酵过程的动力学特征。
Base on the experimental data of batch fermentation in 5 L fermentation reactor, the batch fementation kinetics for Conjugated linoleic acid by Lactobacillus plantarum was investigated, and a series kinetics models were put forward based on the Logitics equation for microorganism growth, conjugated linoleic acid formation and substrate consumption.The experiment data was processed with the Origin 6.1software, the batch fementation kinetics model parameter was obtained.The result showed that the model and th...
