对超滤技术分离辣根过氧化物酶的工艺条件进行了系统研究。利用参数扫描超滤定量分析了超滤操作条件对蛋白质透过率的影响。这些条件包括溶液pH、离子强度、搅拌速度和渗透通量。在优化的工艺条件下,辣根过氧化物酶(HRP)的纯度大于84%,两级超滤后,HRP的回收率接近90%。然后通过等电聚焦、SDS-PAGE和圆二色性分析所得过氧化物酶产物,以确认其等电点、分子量和分子二级结构。并测定了钙离子对HRP比活力的影响。
The optimization of operating parameters for the isolation of peroxidase from horseradish (Armoracia rusticana) roots with ultrafiltration (UF) technology was systemically studied. The effects of UF operating conditions on the transmission of proteins were quantified using the parameter scanning UF. These conditions included solution pH, ionic strength, stirring speed and permeate flux. Under optimized conditions, the purity of horseradish peroxidase (HRP) obtained was greater than 84 % after a two-stage UF process and the recovery of HRP from the feedstock was close to 90 %. The resulting peroxidase product was then analysed by isoelectric focusing, SDS–PAGE and circular dichroism, to confirm its isoelectric point, molecular weight and molecular secondary structure. The effects of calcium ion on HRP specific activities were also experimentally determined.
