ABSTRACT:
A process for the liquid phase adsorptive separation of phenylalanine from a fermentation broth feed containing phenylalanine and salts. The feed is contacted with a Y zeolite adsorbent, exchanged with sodium, potassium or calcium ions, to selectively adsorb the phenylalanine onto said adsorbent to the substantial exclusion of the other feed components and recovering phenylalanine by desorbing with water. Phosphate salts can be recovered in the raffinate in the adsorption process by washing the adsorbent with acetic acid prior to use.
