Abstract
This invention relates to a method for separating basic amino acids from fermentation broth comprising contacting the broth with strong acid cation exchange resins that have a low degree of cross-linkage and eluting the amino acid. The method described herein results in higher yield and higher purity of lysine, in addition to higher throughput, as compared to conventional processes of purification of lysine from fermentation broth.
