Synthesis of Amphiphilic Polymer Particles by Seed Polymerization and Their Application for Lipase Immobilization

摘要: To develop excellent immobilized enzymes, monodisperse amphiphilic polymer particles that have both hydrophilic guanidino groups and hydrophobic acyl were synthesized characterized. The particles, which had an average diameter of 7.92 μm, macropores with diameters ranging from 50 nm to 500 nm. amount Rhizopus delemar lipase on the was 150-8 700 times those lipases prepared by previous investigators using Dowex MWA-1, porous glass beads, Sepharose 4B. specific transesterification activity 93.4 lyophilized lipase.
