ABSTRACT:
A method of producing enzyme preparations having L-.alpha.-amino acyl amidase activity comprising cultivating a micro-organism selected from the group consisting of Pseudomonas putida, Pseudomonas reptilivora, and Pseudomonas arvilla in a nutrient medium and separating an enzyme preparation from said nutrient medium.
A process of preparing L-.alpha.-amino acid and D-.alpha.-amino acid amide from DL-.alpha.-amino acid amide by contacting said DL-.alpha.-amino acid amide with an enzyme preparation obtained by cultivating a micro-organism selected from the group consisting of Pseudomonas putida, Pseudomonas reptilivora, and Pseudomonas arvilla in the presence of a nutrient medium and separating the L-.alpha.-amino acid and D-.alpha.-amino acid amide thus formed.
