Through a variety of resin filter, adsorption and elution conditions for the optimization, as well as decolorization, crystallization methods of research, this article eventually determine the strong acid cation resin HZ-001 which is at pH 3, 3BV / h, having the largest adsorption to the tryptophan; the fermentation broth were centrifuged to remove sediment,then treated with activated carbon to be decolored and then treated with strong acid cation resin HZ-001. After that,2mol/l amino acid were passed through the HZ-001 ion exchanging column,kept almost constants when the flow rate stayed 6 BV / h.
