Abstract (en)
[origin: WO2006108662A1] The invention relates to a method for recovering a basic amino acid from the fermentation liquor of a micro-organism strain that produces the basic amino acid. According to said method: a) the fermentation liquor is acidified with an acid, whose pKs value in water at 25 °C ranges between 2 and 5; and b) the basic amino acid is separated from the aqueous liquor obtained in step a) by the successive charging of a single or multiple stage, serial arrangement of a strongly acidic cation exchanger in the form of a salt with the liquor that has been obtained in step a) and the subsequent elution of the basic amino acid using a basic eluant.
