摘要：An optically active amino acid is useful as food or feed, agrochemicals, chemicalproducts for industrial use, intermediates for synthesis of cosmetics or medicines and thelike and is also important as optical resolving agents or chiral building blocks for use inorganic synthesis. Thus, the object is to provide an industrially practical method forproducing the optically active amino acid simply and at low cost. The method comprisesthe step of reacting an aminonitrile composed of a mixture of a D-aminonitrile and an L-aminonitrile with a biocatalyst which is one derived from a newly isolated microorganismbelonging to the genus and has an activity of converting the two aminonitriles into a D-amino acid amide and an L-amino acid amide respectively, a biocatalyst which has anactivity of racemizing the D-amino acid amide and the L-amino acid amide to each other,and a biocatalyst which has an activity of converting one of the D-amino acid amide andthe L-amino acid amide into the corresponding D- or L-amino acid.
