Based on the solubility data, the phase diagram of the system was plotted, which consists of three univariant curves E1E, E2E and E3E, one invariant point E and three crystallization fields: KCl, K2B4O74H2O and K2SO4 The experimental result s show that potassium chloride had the salting-out effect on potassium borate (K2B4O74H2O), and potassium sulphate (K2SO4) Meanwhile, the law of density was discussed briefly.

根据实验数据绘制了相应的相图。相图中有一个共饱点E，三条单变曲线E1E，E2E和E3E；三个结晶区平衡固相分别为：K2B4O74H2O，K2SO4和KCl。实验结果表明KCl对K2B4O74H2O和K2SO4有盐析作用，并简要讨论了密度变化规律。

Both the bacterial culture and aseptic filtrate showed activities to inhibit some pathogenic fungi including "Alternaria alternata", and "Fusarium graminearum" on activity plates assay. Antagonistic crude protein extract was obtained by 70% ammonium sulphate precipitation, and it was thermostable, unsensible to proteinase K and pepsin, and capable to induce the hypha lysis and cytoplasm condensation of "F. graminearum".

经平皿测试表明，多粘芽孢杆菌P-FS08菌株及其无滤液对烟草赤星病菌、小麦赤霉病菌等多种植物病原真菌均有抑制作用。P-FS08培养液通过70%硫酸铵沉淀得到具有拮抗活性的蛋白粗提液，其具有良好的热稳定性；对蛋白酶K和胃蛋白酶均不敏感；够使小麦赤霉病菌菌丝断裂，原生质浓缩。

The culture filtrate of strain LN-176 was tested for light absorption at 260nm and 280nm, and the results showed that the protein content in the culture filtrate significantly increased. After ammonium sulphate precipitation, the supernatant and the precipitation were separated to testify their antagonistic activity, and it was found that the precipitation was inhibitory to Ustilago hordeum , but the supernatant not.

LN-176菌株的发酵液在260nm和280nm下进行吸光度测定，结果表明发酵液中蛋白质含量明显升高；发酵液经硫酸铵盐析后，取上清液和沉淀物分别做抗菌试验，发现沉淀物对青稞散黑穗病菌有拮抗活性而上清液无活性。
