摘　　要：研究了高沸醇木质素、高沸醇木质素酚、高沸醇木质素胺和木质素树脂对菠萝蛋白酶和木瓜蛋白酶的吸附性能,结果表明:这几种木质素类吸附剂都可以吸附菠萝蛋白酶和木瓜蛋白酶;经改性的高沸醇木质素胺和高沸醇木质素酚的吸附性能优于高沸醇木质素和木质素树脂,且吸附后的酶还能保持较高的活性,高沸醇木质素衍生物有望成为菠萝蛋白酶和木瓜蛋白酶的浓缩吸附剂或固定化的载体。The adsorption of HBS lignin, HBS lignin phenol, HBS lignin amine and lignin resin with bromelain and papain were studied. The results showed that the four kinds adsorbent of lignin were able to adsorped bromelain and papain,the adsorption abilities of amine and phenol derivatives of HBS lignin were better than HBS lignin and lignin resin. The activities of the bromelain and papain were kept a certain degree after the adsorption. The HBS lignin derivatives could be used as new concentrate absorbents of bromelain and papain or new carriers in bromelain and papain immobilization.
