L-aminoacid oxidase from yeasts of the genus cryptococcus, their preparation and use

摘要

Yeasts of the genus cryptococcus, preferably of the species C. Laurentii, form, in the presence of aminoacids, an L-aminoacid oxidase which stereospecifically converts L-aminoacids and their derivatives into the corresponding alpha -ketoacids. The immobilized cells are advantageously used for this conversion, which can also be used to resolve racemates.
