As to the high polarity, high boiling point resultant—trimesic acid, the analysis methods of infrared spetrum, gas chromatography-mass spectroscopy, vapour-phase chromatography, acid number titration and so on are seperately used to characterize its property. Infrared spetrum and gas chromatography-mass spectroscopy are used to have a qualitative analysis on the resultant and are compared with the stand diagram. Sulfuric acid-methanol esterification and rapid esterification are used to prepare the trimesic acid trimethyl-ester and have a FID quantitative analysis. So that we make sure the purity of trimesic acid in the resultant and also we have an acid alkali titration on the resultant to get its acid number, in order to verify the purity of trimesic acid in the resultant.

During growth phase the metabolic flux to glycerol synthesis was much large, and the carbon was mostly catabolized in TCA in the glycerol production process. With large flux through TCA cycle ATP could be overproduced by NADH oxidation and most ATP may be in futile cycle, which may be the reason that the yield of glycerol is hard to be improved.

分析发现菌体生长阶段合成丙三醇的代谢流较大,这可能是细胞为了维持高渗透压环境下正常生理功能所需;但是在菌体生长停止后,产丙三醇阶段合成丙三醇的代谢流并没有增加,而是TCA循环中代谢流增加,于是产生的NADH氧化生成更多ATP,大都ATP可能是无效循环消耗掉,这是丙三醇产率没有达到理想产率的根本所在。

Theresults indicated that the initial desorption rate of As was higher than As, but thefinal desorption percentage of As was two times higher than As; that in therange of pH(6.5-8.5), the desorption of As was the lowest(pH=6.5),and thepercentage increased with the pH value increasing or deescalating, but for the As,thepercentage increased with the increase of pH; that the supersonic accelerated desoptionof arsenic and the final percentage was lower than non-supersonic; that on the conditionof UV-light ,in a word, it took negative effect to desorption The"reproduced process"has been used in the procedure of regeneration.

实验结果表明,初始阶段,三价砷的脱附率高于五价砷,但最终脱附率三价砷低于五价砷;三价砷、五价砷在不同温度下的脱附实验表明三价砷的最佳脱附温度低于五价砷的最佳脱附温度;在pH=5.5-8.5时,随着pH的增大,五价砷的脱附率具有先减小再增大的趋势,在pH为6.5时脱附率降至最小;在pH=5.5-8.5时,三价砷的脱附率随pH的增大而增大;不论是三价砷还是五价砷的脱附过程,超声波条件都会促进脱附速率(来源:ecABC论a4文网www.abclunwen.com)的增加,并且最终的脱附率要高于无超声波条件下的脱附率;紫外光照条件下,随着光照时间的增加,两种价态砷的脱附率会达到一个较高的值,再降低。总体而言,紫外光照的存在不利于脱附的进行。

In this paper, the stable Au complexes are classified according to the coordination atoms and their structural characteristics. The recent development of the researches on the antitumor activity of Au complexes including the structure-activity relationships, biological targets and the mechanisms of action are reviewed. The structure of the coordination ligand and the leaving group have great impact on the in vitro cytotoxicity of the Au complex. Many physical and biological methods are introduced to study the interaction between the Au complexe and the suspected bio-target, such as DNA, protein, mitochondrion, thio-containing biomolecules, etc. The interaction modes (intercalating, electrostatic interaction, covalent bonding, etc.) are focused to illustrate the reason for the antitumor activity of Au complexes.
