摘要

本文中描述的实验向学生介绍了作用于天然底物的酶(β-半乳糖苷酶或乳糖酶)的实际应用。将酶固定在廉价的载体上,固定化衍生物在填充床反应器中用于连续乳糖水解。并与间歇式间歇式可溶酶反应器的实验结果进行了比较。建立了两种反应器的数学模型,并与实验结果进行了比较。

β-Galactosidase immobilization for milk lactose hydrolysis: a simple experimental and modelling study of batch and continuous reactors

The experiment described in this paper introduces students to the practical use of an enzyme (β-galactosidase, or lactase) acting on a natural substrate. The enzyme is immobilized onto a cheap support, and the immobilized derivative is used in a packed-bed reactor for continuous milk lactose hydrolysis. The results are compared to those obtained for discontinuous batch reactors with soluble enzyme. A mathematical model of the two types of reactors is run, and its results are compared with the experimental data obtained.
