In this paper , cefadroxil was synthesized in [Bmim][NTf2]‐ phosphate cosolvent using immobilized penicillin G acylase on micron‐size magnetic polymer microspheres with the high S/H ratio of 1.12 and 79.0% yield. The results illuminated that there are two very critical and essential designs i.e. effective support and suitable solvent system in enzymatic synthesis of cefadroxil.
