A process for making D-aminoacylse includes adding 1% N-acetyl-DL-amino acid preferably N-acetyl-DL-methionine and N-acetyl-DL-leucine in a culturing medium incubated with bacteria selected from the strain of Alcaligenes faecalis for culturing the bacteria and for inductively promoting an enzyme reaction to produce the D-aminoacylase which is able to hydrolyze D-amino acids and unable to hydrolyze L-amino acids.
