Process for preparing D-N-carbamoyl-.alpha.-amino acids
 A process for preparing D-N-carbamoyl-.alpha.-amino acids by subjecting 5-substituted hydantoins to the action of a cultured broth, cells or treated cells of microorganisms having an ability in asymmetrically hydrolyzing the hydantoin ring in an aqueous medium of pH 7 to 10. The process is suited for the industrial manufacture of D-N-carbamoyl-.alpha.-amino acids which are useful intermediates for the preparation of medicines.
