ABSTRACT:
A method for separating a basic amino acid from its fermentation broth, or the liquid resulting from the intermediate treatment of the fermentation broth, containing high-molecular weight contaminants which entails permeating the broth, or liquids resulting from the intermediate treatment of the broth, through a semi-permeable membrane, until the basic amino acid is separated from the high-molecular weight contaminants, by passing through the membrane in the permeate; contacting the permeate with a strongly acidic cation exchange resin; and eluting the adsorbed basic amino acid from the cation exchange resin.
