Abstract : Flower-like
Fe3O4 microspheres prepared by a fast solvothermal method
were selected to fabricate micron-sized Fe3O4@glycidyl
methacrylate (GMA) magnetic porous microspheres. The magnetic porous
microspheres were endowed with appropriate specific surface area (39.54 m2 g?1) and appropriate pore diameter (16 nm), and could serve as a
carrier for immobilized lipase. Meanwhile, the prepared magnetic microspheres
with high saturation magnetization could realize rapid separations. After those
microspheres were aminated and activated, the obtained immobilized lipase
possessed high efficiency of immobilization and catalytic activity, with the
optimum pH and temperature of 8.0 and 40 °C, respectively. The thermal
stability of immobilized lipase was obviously exceeding free lipase.
