In addition, a further study was made of the technique of extraction, isolation and purification of GLA. The factional extraction used in the laboratory with n-hexane and ethanol was changed into the whole extraction of 6〓 solvent, which simplified production technique and reduced cost of production. The fungal lipid extracted from the fermentation in the medium-scale test was concentrated by the urea adducting method with methanol as solvent, at 75~80℃ for 3 hours. After GLA had been adducted twice, the content of GLA came up to 84. 25%, around a twelfth as much as the original concentration.

并对γ—亚麻酸的提取和分离纯化工艺进行了研究,将实验室中用正己烷和乙醇分步抽提的工艺改为用6〓溶剂一步抽提技术,从而简化了生产工艺,降低了生产成本;采用脲素包合法,以甲醇作为溶剂,温度控制在75~80℃,包合时间为3h,对中试发酵所提取的菌油进行了浓缩,γ—亚麻酸两次包合后,GLA含量达到84.25%,比原浓度浓缩了近十二倍。

Extracted DNA by CTAB, in proportion to the additions of PVP and β-mercap toethanol to the extraction buffer were capable of preventing browning from taking place in the extraction, Tris-Phenol (Stabilized with 0.1M Tris, pH 8.0)/Chloroform/isoamyl alcohol were used to remove protein and impurity in the second extraction, during crude DNA used to Isopropanol DNA and deterged by DNA detergent, without using RNase remove RNA, we detected the quality and concentration of DNA respectively for normal leaves and drought stress leaves by Agarose gel electrophoresis of genomic DNA and ultraviolet spectrometry photo.

用20%聚乙二醇(polyethylene glycol,PEG6000)模拟干旱,采取CTAB提取缓冲液,按一定比例加入PVP和β-巯基乙醇,用Tris平衡酚-氯仿-异戊醇除去蛋白质及杂质,在粗提时用异丙醇沉淀DNA,并用DNA洗液(10mmol/L醋酸铵,75%乙醇)洗涤DNA,在纯化时用乙醇沉淀DNA,且没有加入RNase去除RNA的方法,分别提取2个品种正常和干旱胁迫的苹果属叶片总DNA,并对提取的DNA进行琼脂糖凝胶电泳和紫外分光光度计检测。

An attempt was made to remove color from simulated wastewaters containing Acid Scarlet GR and Reactive violet K-3R by cloud point extraction using a nonionic surfactant of Triton X-114. The influence of the concentrations, equilibrium temperature and equilibrium time on the extraction efficiency was tested. The experimental results show that the extraction efficiency to dye increases with increasing concentration of TX-114 and salt or decreasing initial dye concentration.

本文选用非离子表面活性剂TX-114作浊点萃取剂,研究了由酸性大红与活性紫构成的单元和二元混合染料模拟有色废水的萃取脱色过程,讨论了表面活性剂浓度、染料浓度、盐浓度、平衡温度、平衡时间等因素对萃取效率的影响结果表明,提高表面活性剂浓度、盐浓度有利于提高萃取效率,而染料浓度增加则使萃取效率略有下降。

The extraction of.watermark used the method of cascade extraction and Variance control, improved the accuracy and rate of extraction.

试验结果表明,算法不仅具有良好的不可见性,并且对常见的图像处置操纵具有较好的鲁棒性。
