Abstract
This process for preparing L .alpha.-amino-acid is characterized in that the corresponding racemic .alpha.-amino-acid is hydrolysed in liquid phase in a free form or in the form of a salt, by an agent containing an L-stereospecific amidase and in that the L .alpha.-amino-acid obtained is separated from the D .alpha.-amino-amid unhydrolysed. This process is appropriate for the preparation of optically active natural amino-acids.
