摘要
从用固定化细胞生产L-苯丙氨酸的反应液中,应用颗粒活性碳分离纯化L-苯丙氨酸。结果表明,该方法不受大量的无机盐干扰,纯化的L-苯丙氨酸,回收率为70%左右,产品纯度大于99.5%。
In this paper, we used active carbon to isolate and purify L-phenylalanine from the reacted liquid of L-phenylalanine produced by immobilized cells. The result indicated: the method can exclude the interference of much inorganic salt and obtain pure L-phenylalanine, the recover ratio is about 70%, the purity of product is more than 99. 5 %. This technique is simple and less time, and the puri ty of L-phenylalanine is high.
