Immobilization of phospholipase D on macroporous SiO/cationic polymer nano-composited support for the highly efficient synthesis of phosphatidylserine.

Novel nano-composites were prepared by coating epoxy resin-based cationic polymer in nano-thickness via in-situ curing on the nano-wall of macroporous SiO with pore size of 0.5∼1 μm. By changing the thickness of polymer coating the specific surface area and porosity varied in range of 115∼74 m/g and 90.
