ABSTRACT:
D-lactic acid is continuously produced by conducting fermentation in a D-lactic acid-producing medium by using as a seed culture a part of a broth obtained in a previous fermentation step of D-lactic acid and elevating a concentration of said growth-promoter to such an effect that a optical purity of the D-lactic acid may be prevented from decreasing. Instead, air may be used.
