FUNCTIONAL COMPOSITE MEMBRANE FORMED BY PHOTORESIST METHOD, ITS MANUFACTURING METHOD AND METHOD OF MANUFACTURING USEFUL SUBSTANCE BY UTILIZING FUNCTIONAL COMPOSITE MEMBRANE

摘要

PROBLEM TO BE SOLVED: To provide a functional composite membrane formed by a photoresist method and two or more layers of phases laminated and having different functions, a method of manufacturing the composite membrane and a method of manufacturing a useful substance by using an enzyme, a protein, etc. and utilizing the composite membrane.;SOLUTION: The composite membrane is formed by a photoresist method comprising dissolving a substance containing glutamate decarboxylase in photo-sensitive polyvinyl alcohol, applying the resultant solution to one side of a cation exchange membrane and drying, and irradiating the resultant membrane with light containing the wavelengths hardening the photo-sensitive resin to polymerize. When the formed composite membrane, CM, is laid at the center of a diffusion dialysis vessel consisting of a chamber F on the Feed side and a chamber S on the Strip side and dialysis is carried out by causing a substrate solution performing an enzymatic reaction to flow on one composite surface to which a functional substance is fixed while causing an electrolyte to flow on the other composite surface, a target substance is produced on the composite surface to which the functional substance is fixed, and a part of the product is recovered in the electrolyte solution on the other side through the composite membrane, leading to simultaneous execution of reaction and separation.;COPYRIGHT: (C)2009,JPO&INPIT
