ABSTRACT The invention relates to a process for the prepar- ation of L-.alpha.-amino acid and D-.alpha.-amino acid amide from DL-.alpha.- amino-acid amide by contacting the DL-.alpha.-amino acid amide in an aqueous solution with an .alpha.-amino acyl amidase containing preparation obtained from a culture of Pseudomonas putida in the presence of traces of bivalent metal ions as activator, characterized in that the aqueous solution also contains a potassium salt selected from the group consisting of potas- sium sulphate and potassium chloride. The invention further relates to a process for the preparation of a L-.alpha.-amino acid and D-.alpha.-amino acid amide starting from the corresponding alde- hyde, potassium cyanide and ammoniumsulphate, subsequent treatment with a ketone and potassiumhydroxide and finally subjecting to enzymatic hydrolysis with a preparation obtained from Pseudomonas putida.
