摘要
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.. or more.
