The present invention relates to a method for producing lactic acid using rice-derived materials such as rice bran, skim steel, rice, chain rice and the like. In the fermentation process to cultivate lactic acid fermentation microorganisms to biosynthesize lactic acid, lactic acid is produced by using a natural medium composed of rice-derived materials without adding other chemicals to the culture medium. The present invention relates to a method for economically mass production of lactic acid, which is an industrially important organic acid, by using rice bran by-products such as rice bran, skim steel, and chain rice. |
