摘要

A kind of macroporous bead carrier of copolymer containing monomer units of N-aminoethyl acrylamide and vinylalcohol was synthesized

i.e. the MR-AA carrier. Papain was immobilized on the carrier using glutaraldehyde as the couplingagent. The enzymatic activity of the immobilized papain was compared with free papain using casein as a substrate

and theeffects of glutaraldehyde concentration

temperature

time and papain amount added on the activity recovery were alsoinvestigated. The results show that the MR-AA carrier contains reactive primary amine groups

hydrophilic amido links and hydroxyl groups

as well as macroporous structures based on its matrix (MR-AV matrix)

furthermore

the activity recovery of papain in the immobilization could reach 48%～58%.In comparison with free papain

the resulting immobilized papain exhibits a remarkable thermostability and better reusability.
