  • Patent number: 6218581
    Abstract: The present invention relates to a process of producing optically active alcohol having high optical purity by performing an enzyme conversion reaction on a raw material serving as the substrate, examples of which include racemic alcohol, ketone and the acylated form of a racemic alcohol, followed by hydrolysis as necessary, using as an optical separation catalyst a immobilized water-soluble protein extracted from inexpensive and safe grains or beans in order to solve the problems of the reaction process consisting of low yield due to the occurrence of side reactions, detrimental effects on the ecosystem and their accompanying cost burden, the need for aseptic procedures and the extended amount of time of subculturing, all of which are problems associated with production processes of optically active alcohols of the prior art that use microorganisms, microorganism enzymes, animal tissue enzymes and cultured plant cells.
