Abstract
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.
