摘要: A novel esterase (molecular weight 54,000.+-.2,000) derived from a microorganism belonging to genus Bacilus is extensively utilizable for organic synthetic reaction, especially for asymmetric hydrolysis of ethyl 2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropane carboxylate (ethyl permethrate), in the same manner as pig liver esterase.The microorganism suitable for production of the above novel esterase is Bacillus sp. DC-1 (FERM BP-1254).
