The third instar larvae of Anomala corpulenta and Holotrichia oblita were injected with a standardized dose of spores of Bacillus popilliae Dutky, and the reactions of hemoeytes were examined during the first 24 hours after the injection. Agglomerates of hemoeytes were formed in all the injected larvae and they attached to the fat body and internal surfaces of the body cavity.In the more susceptible larvae of Anomala corpulenta, hemoeytes formed clumps and the cells underwent lysis to yield the melanian acellular...

The third instar larvae of Anomala corpulenta and Holotrichia oblita were injected with a standardized dose of spores of Bacillus popilliae Dutky, and the reactions of hemoeytes were examined during the first 24 hours after the injection. Agglomerates of hemoeytes were formed in all the injected larvae and they attached to the fat body and internal surfaces of the body cavity.In the more susceptible larvae of Anomala corpulenta, hemoeytes formed clumps and the cells underwent lysis to yield the melanian acellular substance. The necrotising masses may become encapsulated by plasmatocytes to form capsules with black cores within 5 min., althouth this encapsulation occurred around a few agglomerates. In the nonsusceptible larvae of Holotrichia oblita, most of clumps consisted of spherule hemoeytes, granular hemoeytes and plasmatocytes and the bacteria. The initial aggregetion stage was very rapid, occurring within 5 min., and it was brought about by the release of an adhesive flocculent material by the spherule hemoeytes in contact with the bacteria. Within 24 hours, we did not found any hemocyte lysis and melanization.The result shows that the responses of the hemoeytes of Anomala corpulenta and Holotrichia oblita to the pathogenic Bacillus can give indication of their natural infective rates, and that encapsulation and clump formation can effectively prevent the-development of the bacterial spores.

The relative mobilities of two proteins bands isolated from TCSP by electrophoresis on 7.5 % polyacrylamide gel (PAGE) containing SDS (SDS-7.5% PAGE) changed with the conditions of extraction. When TCSP was resolved by SDS 10-12.5% PAGE or by SDS-7.5% PAGE after treatment with phenolacetic acid-water (2:1:1 by volume; PAW) four bands were found.The freeze-dried TCSP was very easily resolubilized by SDS, but only with difficulty when defated by chloroform-methanol (2:1, by volume; CM)or dehydrated by acetone. In the latter case only one band could be found by SDS-7.5% PAGE. After treatment with PAW, the defated and dehydrated TCSP was resolved into three bands by SDS-7.5 % PAGE.By sequential fractionation of TCSP with CM, 10 mM Tris-HCl-buffered 0.15 M NaCl solution (pH 7.5; TS), and 0.1 N NaOH solution (AS), it was found that TCSP was a complex composed of approximately 10 % CM soluble protein (CMP), 30 % TS soluble protein (TSP), 60 % AS solubel protein (ASP), and some alkaline insoluble substances.The CM-extracted fraction contained about 70% protein and 30% neutral sugar, but did not contain any phospholipid and esterified fatty acids. It showed an ultraviolet absorption peak near 260 nm with a shoulder at 320 nm. Four components could be detected by chromatography on Sephadex LH-20 column. Based on the shape of the absorption peaks, these components could be divided into two groups.Enzyme activities of peroxidases, esterases, phosphatases, and ATPase were detected in TSP.A yellowish semi-opaque precipitate was obtained when 10% acetic acid in absolute ethyl alcohol (1:4, by volume) was added to AS extracts. When the precipitate was dissolved in AS and dialyzed against deionized water for 36 hr, then freeze-dried, a silk-like glittering flocculent substance was obtained. The substance was water-soluble and viscous. On Sepharose-4 B chromatogarphy, two peaks were shown in the eluate. Two bands (TCSP-Ⅰ and TCSP-Ⅱ) were separated by SDS-7.5 % PAGE. While with SDS-10 % PAGE, TCSP-Ⅱ appeared prodominantly and its molecular weight was approximately 1.5×10~5.When examined under microscope, yellow globular granules arranged closely on the surface of TCSP were observed when TCSP was suspended in water. These granules could be removed by CM extraction, and then the surface became more smooth. Upon TS extraction, the surface appeared striped with silklike structure. When it was further extracted by AS, some fibrous residues remained.

用有机溶剂CM、Tris-HCl缓冲(pH7.5)的生理盐水(TS)和稀碱(AS)溶液分类分离烟草细胞表面蛋白,发现含有10%左右的CM蛋白,30%左右的TS蛋白,60%左右的AS蛋白和一些未经鉴定的碱不溶性物质(AIS)。 CM蛋白的紫外吸收光谱分析,在波长260 nm附近有一吸收峰,波长320 nm处有一个肩,Sephadex LH-20亲脂性柱层析可分离出四个组分,按其光谱特性可分成两大类。TS蛋白主要是一些水解酶,已测出的有过氧化物酶,酯酶、磷酸酶和腺甙三磷酸酶。AS蛋白在Sepharose 4B柱上可分离出两个洗脱峰,SDS-10%聚丙烯酰胺凝胶电泳分离结果表明,主带分子量接近1.5×10~5道尔顿。 显微镜下观察TCSP及其用CM、TS和AS相继提取后的残存物形态,看到悬浮在无离子水中的TCSP表面密布黄色球形颗粒。CM提取后颗粒消失,出现比较平滑的表面。TS提取后残存物表面出现纹理结构和丝状物。AS提取后剩下的是一束束解开的纤维状物质。

In a steadily operating vertical secondary clarifier, there exist a sludge-water interface and a compressive interface and four zones of different settling characteristics :.a clarified zone, a flocculent settling zone, a transition zone and a compressive zone. For a given sludge, the position of sludge-water interface depands on the upflow velocity , and the position of the compressive interface depands on the concentration and the velocity of under - flow . Generally, the sludge - water interface which contributes to clarifying ability is primarily influenced by the surface area of the tank , and the height of water surface above the inlet is the secondary factor . As to the compressive interface which contributes to compressive ability , the depth below the inlet is the primary and the surface area is the secondary factor.

稳定运行的竖流式二沉池中存在着泥水界面和压缩界面,以及沉淀性质不同的四个区,在污泥性质一定的条件下,泥水界面位置由上升流速决定,压缩界面位置由底流浓度和底流速度决定。一般地说,对于前者,面积是第一位因素,进水口之上高度是第二位因素,构成澄清能力;对于后者,进水口之下高度是第一位因素,面积是第二位因素,构成浓缩能力。
