A process for preparing D-(-)-N-carbamoyl-2-(phenyl or substituted phenyl)glycines by subjecting 5-(phenyl or substituted phenyl)hydantoins to the action of a cultured broth, cells or treated cells of microorganisms having a capability in asymmetrically hydrolyzing the hydantoin ring. D-(-)-N-carbamoyl-2-(phenyl or substituted phenyl)glycines are useful intermediates of medicines and can be readily converted to D-(-)-2-(phenyl or substituted phenyl) glycines known as available intermediates of antibiotics.
