摘要:

本实验分别利用 Logistic 方程和Luedeking-Piret 方程描述低温淀粉酶产生菌LA7 的发酵过程,建立菌体生长、低温淀粉酶生成和底物消耗的动力学模型,对模型预测值与实验值进行比较。结果表明,模型能较好地拟合发酵过程,具有良好的适用性。

Abstract:

The fermentation process of col- active amylase production by LA7 was studied. Based on Logistic equation and Luedeking-Piret equation, the kinetic models for cell growth, cold active amylase production and substrate consumption were established, and the predictive values of models were compared with the experimental data. Results showed that they match well and the models are applicable in the cold-active amylase fermentation process.

Key words: cold-active amylase, fermentation, kinetic model
