Method of increasing the yield based on sugar or optical purity of lactic acid in D- and lactic acid production method of lactic acid D-

摘要

And provides a method for increasing the optical purity of lactic acid and a process for preparing a D- lactic acid by culturing the assimilated by microorganisms molasses with SOLVED] Purification of D- lactic acid. A method of manufacturing a D- lactic acid by culturing and by assimilating microorganisms SOLUTION: A molasses, the method having the step of purifying the molasses by using ion-exchange resin method, for producing a D- lactic is. As a result, the optical purity of lactic acid D- 99.40% e. e. It can be produced efficiently or more lactic acid.
