ABSTRACT:
D-.alpha.-amino acids are produced by contacting a 5-substituted hydantoin with an effective amount of an enzyme capable of converting the 5-substituted hydantoin to the D-.alpha.-amino acid produced by a microorganism in an aqueous medium at a pH in the range of 4 to 9, the microorganism being capable of utilizing the D-isomer of the 5-substituted hydantoin as the sole nitrogen source, but substantially incapable of utilizing the L-isomer of the 5-substituted hydantoin as the nitrogen source and the substituent of the 5-position being such that upon reaction with the enzyme, an optically active D-.alpha.-amino acid isomer is produced; and recovering the D-.alpha.-amino acid which accumulates in the aqueous medium.
