Immobilization and property of penicillin G acylase on amino functionalized magnetic Ni_0.3Mg_0.4Zn_0.3Fe₂O₄ nanoparticles prepared via the rapid combustion process.

ABSTRACT: Penicillin G acylase plays an important role in the biocatalytic process of semi-synthetic penicillin. In order to overcome the disadvantages of free enzymes and improve the catalytic performance of enzymes, it is a new method to immobilize enzymes on carrier materials. And magnetic materials have the characteristics of easy separation. In the present study, the Magnetic Ni_0.3Mg_0.4Zn_0.3Fe₂O₄ nanoparticles were successfully prepared by a rapid-combustion method and calcined at 400°C for 2 h. The surface of the nanoparticles was modified with sodium silicate hydrate, and the PGA was covalently bound to the carrier particles through the cross-linking of glutaraldehyde. The results showed that the activity of immobilized PGA reached 7121.0
