METHOD FOR SEPARATING BASIC AMINO ACID FROM FERMENTATION BROTH

摘要

PROBLEM TO BE SOLVED: To provide a method for separating a basic amino acid from a fermentation broth.

SOLUTION: The method includes a step of contacting the broth with strong acid cation exchange resins having a low degree of cross-linkage and a step of eluting the amino acid. The method 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. The invention relates to providing a method for separating the basic amino acid from the fermentation broth using a simulated moving bed apparatus.
