Immobilization of Aspergillus Oryzae B-galactosidase on Porous Magnetic Poly (GMA-DVB) Particles via Suspension Polymerization

Sufang Sun, Lulu Peng, Xuejie Ming


The porous ferric GMA-DVB polymer was synthesized from glycidlymethacrylate (GMA) and divinyl benzene (DVB) by suspension polymerization with lauryl alcohol and cyclohexanol as pore-forming reagents in the presence of FeCl3 and FeCl2. The structure and the magnetism of the GMA-DVB polymer beads were featured with magnetic scales, X-ray spectroscopy and scanning electron microscope (SEM). Aspergillus Oryzae B-galactosidase was bounded on the magnetic polymer under the best terms, and the maximum activity was determined to be 271.25U/g dry carries. Meanwhile, the fundamental properties about the bounded enzyme, such as the influence of temperature and pH, were assayed and the satisfactory results were got.
