  • Preparation process of optically active .alpha.-aminated acids by biological hydrolysis of nitriles
    Patent number: 4366250
    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.
