Process for the separation of a basic amino acid from a fermentation broth using cation exchange resins

A process for separating basic amino acids from a liquid containing the same using cation exchange resin towers in series, which comprises effecting repetitive adsorption and elution steps in sequence, wherein the washing water employed in said adsorption and elution steps is obtained by recycling t...

Beschreibung
Zusammenfassung:	A process for separating basic amino acids from a liquid containing the same using cation exchange resin towers in series, which comprises effecting repetitive adsorption and elution steps in sequence, wherein the washing water employed in said adsorption and elution steps is obtained by recycling the latter portion of a liquid discharged from a first tower of the adsorption step into an adsorption step in a subsequent cycle, or by recycling a liquid discharged from a first tower at the elution step into an elution step in a subsequent cycle.
