Novel strain producing d-lactic acid and use thereof

The present invention relates to a method for producing a mutated strain which produces D-lactic acid, to a mutated strain producing D-lactic acid which is produced by the method, and to a method for producing D-lactic acid comprising the steps of culturing the strain and obtaining D-lactic acid from the culture, wherein the method for producing the mutated strain comprises the steps of: inhibiting the activity of L-lactic acid dehydrogenase (L-LDH) in a strain producing L-lactic acid; and introducing D-lactic acid dehydrogenase (D-LDH) activity. Since the D-lactic acid producing strain of the present invention is produced by mutating a strain having excellent L-lactic acid producibility to have excellent D-lactic acid producibility, the present invention can be widely applied to increasing the producibility of various articles which use D-lactic acid as a raw material.
