谷氨酸发酵液的絮凝过滤研究

Studies on Flocculent Filtration of Fermentation Broth of Glutamic Acid

对用壳聚糖絮凝处理谷氨酸发酵液的方法进行研究 ,讨论了 p H值、絮凝剂浓度、温度和搅拌时间对处理效果的影响。实验结果表明 :最佳工艺条件是壳聚糖浓度 1 0 0 ppm,p H5～ 6,在 30～60℃搅拌 1

This paper studies the pretreatment of glutamic acid broth.Optimum conditions of the flocculate are dis- cussed.The bestresultis obtained atchitosan 1 0 0 ppm,p H5～ 6,30～ 60℃ ,and stirring 1 5min.
