摘要：
The present invention relates to a process for producing D-lactic acid and L-lactamide, comprising allowing a culture broth of a microorganism capable of asymmetric hydrolysis of DL-lactamide belonging to the genus Alcaligenes, Pseudomonas, Agrobacterium, Brevibacterium, Acinetobacter, Corynebacterium, Enterobacter, Micrococcus or Rhodococcus, the microorganism itself, a material obtained therefrom or an immobilized material thereof to act on DL-lactamide, and recovering the resulting D-lactic acid and the remaining L-lactamide. The present invention enables sufficient production of D-lactic acid and L-lactamide by the present microorganism.
