摘要
简要介绍了谷氨酸传统发酵工艺中存在的问题以及膜分离技术,研究了超滤膜与纳滤膜分离技术在谷氨酸发酵液去除蛋白及菌丝体过程中的应用,通过对超滤膜通量、超滤膜质量、废液的排放情况以及超滤系统工艺的适应性、超滤浓缩倍数和滤渣含水量、超滤收率、系统的可恢复性能、纳滤浓缩情况等指标的综合研究,同时综合考虑经济效益和环保效益,得出了超滤膜及纳滤膜分离技术在对谷氨酸提取工艺改进方面具备可行性的结论.
It was given the problems in the tradition fermentation of glutamic acid and an outline of membrane separation technique,studied the application of ultrafiltration membrane and nanofiltration membrane separation technologies in the fermentation broth of glutamic acid on deleting protein and mycelium.By the studies of those index：membrane flux,quality,the discharge of waste liquor,the suitability of ultra filtration system techniques,cyclw of concentration moisture content of the cake,the yield of ultra filtration,the restorability of the system,the concentration of nanofiltration.While from the aspects of economic and environmental benefits,it found that ultra filtration and nanofiltration membrane separation technologies on the extraction of glutamic acid with the feasibility of improvement.
