Abstract
A method of recovering an amino acid from a mixture by providing a source of bivalent metal ions capable of forming a complex with the amino acid, the complex being insoluble at least in a particular pH range. The complex is separated from the mixture and then dissociated, the metal ions thereby being removed from the amino acid. The amino acid may be recovered continuously from a fermentation broth of microorganisms.
