High percentage of chlamydospore germination of Neovossia horrida (Tak.)P.& K.with abundant basidiospore production was obtained by placing moistenedspores in a Petri dish with limited supply of water,the dish-cover being inkedblue to insure a favordable light condition.Moistened spores applied on the sur-face of kernels of a growing rice head enclosed in a paraffin paper bag was alsofound to germinate by producing a very short basidium and a large number ofbasidiospores.It is,therefore,concluded that not only light but also oxygen isrequired for normal germination of the spores of the rice kernel smut. Results of a series of inoculation experiments conclusively show that thefungus infects rice kernels during the milky dough stage.Basidiospore inoculationgives higher percentage of infection than chlamydospore inoculation. Field observation indicates that the incidence of high percentage of infectionis coincident with the excessive application of nitrogenous fertilizer.Fluctuationof the amount of infection from year to year is probably determined chiefly by theduration of high moisture period from heading to dough stage.There are someevidences of varietal difference in the susceptibility of rice to the kernel smut.

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...

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。

Hydrocarbon type distribution of the narrow cuts of acid-treated gas oil fraction (166~350℃) from Fushun shale oil crude is studied by use of distillation, adsorption and urea extractive crystallization techniques. 89—90% by weight of hydrocarbons and 10—11% by weight of non-hydrocarbons are found in each narrow cut.

Hydrocarbon type distribution of the narrow cuts of acid-treated gas oil fraction (166~350℃) from Fushun shale oil crude is studied by use of distillation, adsorption and urea extractive crystallization techniques. 89—90% by weight of hydrocarbons and 10—11% by weight of non-hydrocarbons are found in each narrow cut. The content of paraffinic and cycloparaffinic hydrocarbons increases from 31.3% to 41.0% as the boiling point of the fractions is raised, and in which two-third of the saturates are composed of paraffins with straight chain structure. The amount of unsaturates is about one-third of each fraction and about half of the unsaturates are olefins of normal structure. The content of aromatics differs slightly in different cuts. In analogous manner, hydrocarbon type composition of wide cut of gas oil (166~350℃) from Fushun shale oil crude is studied, except that the separation of hydrocarbons and non-hydrocarbons is effected by elution chromatography instead of acid treatment. The hydrocarbons thus obtained amount to 73.5%, whereas non-hydrocarbons are 26.5% (with nitrogenous compounds predominating). In the hydrocarbon portion, normal paraffinic, cycloparaffinic and branched paraffinic, normal olefinic, isoolefinic and cycloolefinic, monocyclic aromatic and polycyclic aromatic hydrocarbons amounts to 20.4, 7.4, 13.9, 12.1, 8.5 and 9.6% respectively. Apart from that, about 1.6% dark colored tarry matter is separated from the hydrocarbon portion. A simplified procedure for the hydrocarbon type analysis of gas oil fraction from shale oil crude by adsorption chromatography is also recommended.

本文首先介紹了撫順頁岩油酸洗油166~350°各窄餾分的化學組成。所應用的研究方法為蒸餾、吸附及尿素結晶抽提等,其中以吸附分離為主.試驗結果說明各餾分含有89~90%(重量)的烴及10~11%的非烴,烷-環烷的含量隨着餾分沸點的昇高而增大,由31.3%增至41.0%,其中正構烷約佔三分二。不飽和烴約佔各餾分的三分之一,其中直鏈烯約佔一半。各餾分中芳煙的含量大致都很接近。又應用類似的方法對撫順頁岩油柴油寬餾分(166~350°)進行了詳細烴族組成研究。不同之處就是應用了粗孔硅膠作為吸附劑的冲洗色譜法代替酸洗祛分離煙與非烴。所得結果烴部分為73.5%,非烴部分為26.5%(以氮化合物為主)。烴部分中有正構烷20.4%,異構烷-環烷7.4%,直鏈烯13.9%,異構烯-環烯12.1%,單環芳烴8.5%及多環芳烴9.6%。烴部分中還分出了1.6%黑色粘稠的非烴物質。還建立了一個測定頁岩油柴油餾分烴族組成的簡易色譜方法。本法用活性細孔硅膠作為吸附劑,分離是以冲洗色譜法為基礎的。
