The action of aureomycin on the respiration of Escherichia coli under different conditions was studied. Our results show that the respiration of Escherichia coli in ordinary broth or in media containing glucose together with some nitrogenous substance such as casein hydrolysate, alanine, aspartate, glutamate, glycine or ammonium sulfate, could be inhibited by aureomycin of minimal growth inhibiting concentration, namely 2.5 μg/ml. In the last case, the uptake of ammonium-nitrogen by the bacteria was also diminished....

The action of aureomycin on the respiration of Escherichia coli under different conditions was studied. Our results show that the respiration of Escherichia coli in ordinary broth or in media containing glucose together with some nitrogenous substance such as casein hydrolysate, alanine, aspartate, glutamate, glycine or ammonium sulfate, could be inhibited by aureomycin of minimal growth inhibiting concentration, namely 2.5 μg/ml. In the last case, the uptake of ammonium-nitrogen by the bacteria was also diminished. Aureomycin of concentrations lower than 100 μg/ml gave no significant effect on the oxygen consumption of the bacteria in a medium containing glucose and phosphate buffer only. Similar results were obtained with pyruvate substituted for glucose and with glutamate as nitrogen source, while with pyruvate alone the oxidation was only slightly depressed by aureomycin (2.5 μg/ml). Malate and acetate oxidations were not inhibited by such low concentration of the antibiotic. In control experiments addition of any of the above mentioned nitrogenous substances to the medium markedly increased the rate of the respiration over that observed for glucose or pyruvate alone, and this increase with the exception of glutamate could not be accounted for by the additional oxidation of the nitrogen containing substrates. In presence of 2.5 μg/ml of aureomycin, this enhancing action of the nitrogenous compounds was strongly depressed. The observed inhibition in case of the substrate mixture cannot be due to the action of the drug on the oxidation of the individual substrates, but is due to processes involving the combined metabolism of glucose (pyruvate) and any one of the nitrogenous compounds. From the fact that the inhibition is clearly noticeable within 15 minutes after the addition of aureomycin and can be observed under conditions in which growth does not take place, as judged from the respiration, it is suggested that aureomycin can inhibit some processes concerned with the oxidative nitrogen metabolism, preceding cell division, of Escherichia coil.

實驗結果表明最低制菌濃度的金黴素可以顯著抑制大腸桿菌在含有葡萄糖和某些合氮物如酪朊水解物、丙氨酸、門冬氨酸、谷氨酸、甘氨酸或硫酸銨的培養基中的呼吸,也抑制了氨氮的同化。在以丙酮酸和谷氨酸作底質時有同樣的現象。以上述含氮物中的任何一種加於大腸桿菌的葡萄糖磷酸鹽緩衝劑的懸浮液中,可以有力地提高其呼吸率,比在單獨葡萄糖中的要高得多。2.5微克/毫升的金黴素可以強烈地抑制這種提高作用。這種觀察到的抑制並不是由於個別底質分别受到抑制的結果。本文討論了金黴素抑制大腸桿菌呼吸的作用機構和可能的幾種解釋,並指出這種作用可能是由於金黴素抑制了包括碳水化物和含氮物在内的某個或某些聯合代謝過程。

Experiments were carried out with a view to ascertaining the most suitabledeoxidation process for basic open-hearth smelting of rail-steel in Anshan works.Itwas found that the amount of oxides inclusions in finished rails was definitely lessif preliminary deoxidation was carried out before tapping,the best results being ob-tained when manganese-silicon alloy alone was used as deoxidizer.Similar rails madefrom heats without preliminary deoxidation were found to contain almost twice theamount of oxides inclusions.The sulphur content of the above rail-steel usually amounted to 0.03-0.04%,theamount of sulphides inclusions is at least equal to,or sometimes double,the amountof oxides inclusions.In such cases sulphides rather than oxides inclusions play thedetermining role for the mechanical properties of the finished rails.As a matter offact,no appreciable difference was observed for rails made by different deoxidationprocesses.Data concerning the size and shape of oxides inclusions in rails made by differentdeoxidation processes have been discussed,and it is pointed out that only in certainspecial cases could the oxygen content of liquid steel prior to tapping provide aqualitative estimation of the amount of oxides inclusions in finished steel products.

本文结合生产,对鞍钢大型碱性平炉冶炼重轨钢的脱氧问题进行了试验。结果指出,在炉池内加脱氧剂进行预先脱氧的重轨成品含氧化物夹杂较少,尤以全部采用矽锰合金做炉池内脱氧剂的效果最佳,而在炉池内不加任何脱氧剂的重轨成品含氧化物夹杂量最多,后者往往超过前者一倍以上。重轨钢合硫一般达0.03—(0.04%,其中硫化物夹杂量与氧化物夹杂量相若,有时甚至达到后者的两倍。在这种情况下,决定钢的机械性能的主要因素是硫化物而不是氧化物,因此不同脱氧方法对重轨成品机械性能的影响不显著。在上述工作中,对重轨成品中氧化物夹杂的形状和大小也进行了分析,并指出在某些情况下铜液含氧量与铜成品中氧化物夹杂数量存在着相适应的关系。

The polymeri2ation of butadiene catalysed by the TiBr4-i-Bu3Al, TiBr4-Et3Al, and TiBr4-BuLi systems has been studied. In the catalyst system of TiBr4-i-Bu3Al with benzene as solvent there are two molar ratios of i-Bu3Al to TiBr4, which exhibit maximum catalytic activity. The gel content, molecular weight and cis-l,4-content of the soluble part of the polymer decrease with increase of the i-Bu3Al/TiBr4 ratio. The catalytic activity seems to be greater, when the monomer is first mixed with i-Bu3Al than first with...

The polymeri2ation of butadiene catalysed by the TiBr4-i-Bu3Al, TiBr4-Et3Al, and TiBr4-BuLi systems has been studied. In the catalyst system of TiBr4-i-Bu3Al with benzene as solvent there are two molar ratios of i-Bu3Al to TiBr4, which exhibit maximum catalytic activity. The gel content, molecular weight and cis-l,4-content of the soluble part of the polymer decrease with increase of the i-Bu3Al/TiBr4 ratio. The catalytic activity seems to be greater, when the monomer is first mixed with i-Bu3Al than first with TiBr4. The maximum activity appears to move towards greater i-Bu3Al/TiBr4 ratio, when the polymerization temperature is lowered. If heptane is used as solvent, the rate of polymerization is reduced and only one catalyst ratio exhibits maximum activity. The gel content, molecular weight and cis-l,4-content of the soluble part of the polymer obtained all seem to be lower. If triethyl aluminium is used instead of triisobutyl aluminium, there are also two catalyst ratios exhibiting maximum activity. When the temperature of polymerization is lower, the catalytic activity of the Et3Al-TiBr4 system seems to be greater than that of the i-Bu3Al-TiBr4 system. The products obtained from both systems appear very alike. They consist of a large amount of gel and the cis-l,4-content of the soluble part of the polymer is below 70%. Catalysed by a new catalytic system-the BuLi-TiBr4 system, butadiene can be polymerized to a product containing the cis-1,4-form higher than 90%. Catalytic activity was observed for BuLi/TiBr4 with molar ratios of 1.5-2.5. The cis-l,4-content of the product becomes smaller, when the catalyst ratio is greater. The valence states of the titanium existing in the above three catalytic systems have been compared. When the metal alkyl to titanium tetrabromide ratio is lower than 2, the trivalent titanium increases with increase of catalyst ratio. When the catalyst ratio is higher than 2, the trivalent titanium decreases with increase of catalyst ratio in the BuLi/TiBr4 system, while in the other two systems the trivalent titanium still increases till 100%. It is interesting to note that the catalytic activity of the BuLi-TiBr4 system lies just between the range of catalyst ratios which possess higher content of trivalent titanium.

本工作研究了四溴化钛与三异丁基铝、三乙基铝或丁基锂组成的催化剂对丁二烯的聚合。结果指出,在三异丁基铝与四溴化钛的系统中以苯为溶剂,有两个铝钛比值呈现最大活性。随铝钛比增加,产物的凝胶及分子量下降,可溶部分顺式-1,4含量亦随之减少。聚合活性以单体先与铝混合较先与钛混合为高。聚合温度降低时最大活性向铝钛比大的区域移动。以庚烷代替苯作为溶剂时,聚合速度降低,仅有一个铝钛比呈现最大活性,产物分子量及凝胶均较低,可溶部分顺式-1,4含量亦较低。如以三乙基铝代替三异丁基铝,则仍有两个铝钛比值呈现最大活性。聚合温度较低时,三乙基铝与四溴化钴的催化活性较三异丁基铝为高。二个系统的大部分产物类似,凝胶较多,可溶部分顺式-1,4含量在70%以下。利用丁基锂与四溴化钛组合的催化系统聚合丁二烯,可得顺式-1,4含量达90%以上的产物。活性范围为锂钛克分子此1.5—2.5。顺式-1,4含量随锂钛比增大而降低。本工作还比较了上述三种催化系统生成低价钛的情况。结果指出,在金属烷基物与四溴化钛的克分子比小于2时,三价钛均随克分子比增大而增大,克分子比大于2时,丁基锂的还原能力随克分子比增加而减少。在其他二种系统中则低价钛继续增加。有意义的...
