PURPOSE: An esterase originating from a microorganism such as Candida or Penicillium is allowed to act on (±)-chrysanthemum-monocarboxylic acid to enable optical resolution into optically active chrysanthemum monocarboxylic acid and the antipode ester with industrial advantage. n CONSTITUTION: An esterase produced by a microorganism is allowed to act on (±)-chrysanthemum-monocarboxylic acid ester. The esterase is produced by a microorganism in Candida, Penicillium, Rhizopus, Trichoderma, Micrococcus, Enterobacter, Pediococcus, Chromobacterium, Mycobacterium, Brevibacterium or Streptomyces and has an ability to effect asymmetric hydrolysis of (±)-chrysanthemum-monocarboxylic ester. After completion of the reaction, the product is collected by solvent extraction, column chromatography or the like. n COPYRIGHT: (C)1985,JPO&Japio |
