Supersonic wave disperse research indicated, ethanediol as the disperse medium, it could got suspending liquid about for firve days, but relatively large in grain size. However, combined use of lauryl sodium sulfate and maleic anhydride as disperse medium, the disperse result among water was better than the former, and it would be steady for two days.
超声分散研究表明,使用聚乙二醇作为分散介质,可得到分散五天左右的悬浮液,但分散后粒度较大,使用十二烷基硫酸钠和顺丁烯二酸酐混合作为分散介质在水中分散效果较好,可稳定两天左右。

The results show that though the strain is growing slower in the nitrogen-free medium than in the nitrogen-containing medium, the content of capsular polysaccharides produced by the strain in the nitrogen-free medium is higher than those in the nitrogen-containing medium, the content of capsular polysaccharides produced by the strain in the nitrogen-free medium is higher than those in the nitrogen-containing medium. The capsular polysaccharides produced by the strain in the culture which contains different mineral powders will reach the highest content on the third or the fourth day in its growing period. The strain's capability of releasing potassium from k-feldspar and biotite in the nitrogen-containing medium is higher than that in the nitrogen-free medium because in the nitrogen-free medium, the strain and its production of glucoprotein are less than those in the nitrogen-containing medium.
结果表明,尽管该菌在无氮培养条件下的菌体数量远小于有氮培养条件,但无氮培养条件下所提取的细菌多糖多于在有氮条件下培养所提取的细菌多糖;胶质芽孢杆菌在以添加钾长石粉或黑云母粉制作的无氮培养基中生长可形成大量多糖,采用丙酮法进行细菌培养液多糖提取,发现细菌培养的第3天所提多糖含量最高;胶质芽孢杆菌在以添加钾长石粉或黑云母粉制作的有氮培养基中生长亦可形成较多的多糖,且在细菌培养的第4天所提多糖含量最高;胶质芽孢杆菌在有氮条件下对含钾矿物的释钾率高于在无氮条件下的释钾率,这可能与该菌在有氮条件下生长更快、可产生较多菌体细胞有关。

Results The data of A were higher in 0.5%, 1%, 2% erythritol culture medium than in xylitol culture medium at the same concentration, while lower in 8%, 12%, 16% erythritol culture medium than in xylitol culture medium at the same concentration. The data of pH were lower in 0.5%, 1%, 2% erythritol culture medium than in xylitol culture medium at the same concentration, while higer in 8%, 12%, 16% erythritol culture medium than in xylitol culture medium at the same concentration.
结果 在0.5%、1%、2%浓度下,赤藓糖醇培养基的A值较木糖醇培养基高,pH值较木糖醇培养基低,说明变异链球菌在含0.5%、1%、2%赤藓糖醇的培养基内的生长和产酸能力明显较相同浓度木糖醇培养基高。

Disperse system:分散体系
分散体系(disperse system)是一种或几种物质高度分散在某种介质中所形成的体系. 被分散的物质称为分散相(disperse phase),而连续的介质称为分散介质(disperse medium). 分散体系按分散相粒子的直径大小可分为小分子真溶液(直径10-7m).
