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. At 60℃,it was condensed into the saturated state and then added Ethanol until its percentage reaching 30%. At 4 ℃ under 100rpm placed in the shaker 20h, the collection of L-tryptophan was dried up in vacuo.

本文通过对种树脂的筛选、吸附和洗脱条件的优化,以及对脱色、结晶方法的研究与摸索,最终确定强酸型阳离子树脂HZ-001在pH=3,3倍床体积流速,温度室温,对色氨酸有最大的吸附作用;将发酵液离心去沉淀并用活性炭脱色后通过HZ-001强酸型阳离子交换树脂柱,再用2mol/L的氨水6倍床体积流速在室温下进行洗脱,收集洗脱液,60℃浓缩为过饱和状态后加入30%无水乙醇,4℃下100rpm摇起晶20h,过滤搜集结晶并真空干燥得白色粉片状L-色氨酸晶体。
