Property or bioactivity of organic compounds is determined by their structure, and stereoselectivity had been one of the key factors in chiral catalysis process. Because of the mild reaction condition, high enantioselectivity, less side reactions and environment pollution of enzyme-catalyzed reactions, utilization of enzymes or microorganisms is of great interest both in economical and social benefits. In this dissertation, the screen of high-yield stereoselective lipase producing strain, production and cha...
