【摘要】 本文对谷氨酸发酵液的提取工艺的改进作了研究。对五种有机絮凝剂在一定pH值、浓度,温度条件下对谷氨酸发酵液的絮凝作用选用L₂₅⁵⁶)的正交试验表进行优选,其最佳效果为:阳离子絮凝剂用量为30-100PPM,pH4和30℃。并对分离方法进行了探讨。实验结果表明絮凝、过滤、离心分离、电渗析方法提取各氨酸是切实可行的。更多还原

【Abstract】 This article studied the improvement of the extraction of the glutamie acid fermentation broth.Optimul conditions of the broth flocculation were obtained with L_25⁵⁶ cross test by using five organic flocculents.We got the best result at the cationic flocculent concentration of 30～100 pm,pH4,and 30℃.The method of separation was also studied.According to the experimental data,a series processing by flocculation、filtration、cenrifugalization and electrodialysis is practical for the recovery of glutamic acid broth.更多还原
