Abstract
Enzymic complexes deriving from micro-organisms belonging to the Bacillaceae family using an hydantoin or a derivative thereof as inductor of the enzymic activity are used for hydrolysing racemic hydantoins into optically active aminoacids. The method of preparation is an enzymic hydrolysis fostered by the enzyme deriving from such special micro-organisms. The hydrolysis can be effected at a comparatively high temperature, which can reach even 60.degree. C.
