A pilot study on desalination of produced water with the combined process of ultrafiltration and electrodialysis 超滤与电渗析联用降低油田采出水矿化度中试试验研究
The research for factors affecting the electrodialyzer operation in amino acid wastewater treatment by bipolar membrane electrodialysis 双极膜电渗析法处理谷氨酸水溶液的过程性能研究
In order to improve the microorganism fermentation process of producing glutamine , an electrodialysis method was developed to separate glutamic acid and glutamine 摘要为改进微生物发酵法生产谷氨酰胺的流程,提出用电渗析方法来分离谷氨酰胺和谷氨酸。
The feasibility of this method was predicted through calculating cation and anion concentrations in typical amino acid mixture solutions , and then validated by electrodialysis experiment 在对混合氨基酸溶液中离子成分进行分析的基础上,预测了此方法的可行性,并通过电渗析方法对模拟发酵液进行实验来验证此预测结果。
Through the theoretical prediction and experiment tests , electrodialysis method could be used directly to separate glutamic acid and glutamine , and a little ammonium sulfate in the mixture benefited the separation process 通过理论预测和实验验证,可以用电渗析法直接分离谷氨酰胺和谷氨酸,且原料中少量的硫酸铵有利于分离过程的进行。
After that a good renature result was obteined using gradient with lower protein concentration . the purity of the recombinant protein by affinity - purification of glutathione sepharose 4b and electrodialysis method was also attained perfect result . the antigenicity of the gst - ha1 protein were identified using elisa mathod 用梯度透析法对变性的融合蛋白gst - ha1进行复性,在低蛋白浓度的条件下,获得了很好的复性结果,复性前蛋白浓度为1 . 02mg ml ,复性后蛋白浓度为0 . 875mg ml 。
