ABSTRACT:
An .alpha.-amino acid is effectively separated and recovered from an aqueous solution containing at least an .alpha.-amino acid and its corresponding .alpha.-amino acid amide by performing ion-exchange electrodialysis in the presence of ammonia. A reaction product liquid obtained by biochemical asymmetric hydrolysis of a D, L-.alpha.-amino acid is used preferably as the raw material aqueous solution for dialysis.
