Title:
METHOD FOR PRODUCING D-LACTIC ACID, AND METHOD FOR INCREASING OPTICAL PURITY OF D-LACTIC ACID OR YIELD OF D-LACTIC ACID RELATIVE TO SUGAR IN LACTIC ACID
Document Type and Number:
WIPO Patent Application WO/2010/084972
Kind Code:
A1
Abstract:
Disclosed is a method for producing D-lactic acid by allowing a microorganism to utilize a purified treacle and culturing the microorganism. Also disclosed is a method for increasing the optical purity of D-lactic acid in lactic acid. Specifically disclosed is a method for producing D-lactic acid by allowing a microorganism to utilize a treacle and culturing the microorganism, which involves a step of purifying the treacle by means of an ion exchange technique. The method enables the efficient production of lactic acid which contains D-lactic acid having an optical purity of 99.40 % e.e. or more.
