摘要:
A process for recovering a high-purity L-amino acid from a fermentation liquor obtained by fermentation or an enzymic method, which comprises removing the impurities contained in said fermentation liquor by passing said fermentation liquor through an ultrafilter membrane and then through an ion-exchange or adsorbent resin; concentrating or cooling the effluent thus obtained to result in crystallization of said L-amino acid, and isolating said crystalline L-amino acid from said fermentation liquor.
