Abstract

Glutamic acid is separated and concentrated from an aqueous liquid also containing other amino acids by passing the liquid through a column packed with a strongly acidic cation exchange resin and through a column packed with an anion exchange resin, treating the glutamic acid-rich fraction so obtained with a weakly basic anion exchange resin, and eluting the glutamic acid adsorbed on the resin with an acid solution. The first two resins may be used in any order, or together as a mixture; when the liquid contains a high proportion of glutamic acid as compared with other amino acids, it is preferable to pass it through a mixture of the first two resins. Suitable starting solutions are Steffen's waste and a fermented broth. Suitable strongly acidic cation exchange resins are "Amberlite" IR-120, Dowex 50, Chempro C-20, "Permutit" Q and Diaion SK 1; suitable anion exchange resins are "Amberlite" IRA-400, "Amberlite" IR-4B, "Amberlite" IR-45, Dowex 1, Duolite A-42 and Diaion SK 100; suitable weakly basic anion exchange resins are "Amberlite" IR-4B and "Amberlite" IR-45 ("Amberlite" and "Permutit" are Registered Trade Marks). The liquid is passed through the first resin to obtain a glutamic acid-rich fraction of the effluent, which is passed through the second resin to obtain a more concentrated glutamic acid-rich fraction (or the liquid is passed through the mixture of the first two resins to obtain a single concentrated fraction), and the latter passed through the third resin. The adsorbed glutamic acid may then be eluted with 1-5 n NCl, and crystallized out by adjusting the pH to 3.2. The overall concentration is about 10 : 1. Examples of the process are given.
