Abstract:
The study showed that the L-argmine-adsorbing capacity of strong-acidic resin 001?7 was 1.135 meq per ml of wet resin by controlling the flow rate of the broth at 1/52 vvm, and the efficiency of the elution was higher by using ammnia water as an eluent at the flow rate of 1/50 vvm. About 160 ml of the above eluant was decolorized with 10 ml of 201?4 resin, the transparance of the decolorized eluant was over 90%, and no adsorption of L-arginine by the 201?4 resin was observed. Under the controlled conditions, the extraction yield of L-arginine reached over 95%.
