摘要
Abstract
Comparing to free enzyme,the catalytic characteristics of immobilizated β-galactosidase were modified. The ranges of optimum reactive conditions have been extended： the influence of temperature became smaller,pH widened to 5.7-6.5 from 5.8-6.2. The conversion rate of substrate becomes higher and the stability of enzyme has been enhanced. Having been re-used for 28 times,the conversion rate of substrate keeps being more than 45%.关键词
