摘要: The invention provides immobilized beta-glucosaccharase and a preparation method application thereof. comprises the following steps of (1) macroporous resin pre-treatment; (2) adsorption NKA-9 polyetherimide surface modification; (3) absorption beta-glucosaccharase; (4) glutaric dialdehyde cross linking reaction modification. metal ion Zn is used as an activating agent heat stabilizer for using first time. Through participation , catalysis efficiency improved by 20 percent or higher; enzyme NKA-9II 92 higher. Relative to initial activity, through after incubation 7h under condition 85 DEG C, activity maintained at value being 80 90 54
