Strains YL001 and YL002 formed a monophyletic clade with strains of X. nematophilus with sequence homology outweighing 99% and the sequence homology to genus Photorhabdus outweighing 94%. The lag, logarithmic, stationary and contabescence phase of the two bacteria were 0-6, 6-18, 18-66 and 66 h respectively; pH of strains YL001 and YL002 reduced to 5.70 and 5.56 at 12 h, respectively, and then rose gradually to 7.74 and 8.07 respectively when culture finished. Glucose content reduced quickly during 0-18 h, and then kept stable. Amido nitrogen content reached the lowest at 12 h and then rose slowly. YL001 exhibited the highest inhibitory effects at 54 h and YL002 exhibited highest inhibitory effects at 42 and 66 h respectively on B. cirerea and B. subtilis. Strains YL001 and YL002 belonged to X.

以杉木胸径生长的年轮指数和太阳黑子自相关因子为输入变量，应用改进的人工神经网络方法建立了太阳黑子相对数年平均值的预测模型，模型的模拟回归优度为 93.3%，预测精度达到 95 。74%。

The antibacterial activities of most of fractions were similar to the pomegranate peel extract.(7) Respiratory inhibition experiment showed that the respiration of thallus was inhibited mainly through the hexose monophosphate pathway, which leaded to be short of NADPH, and induced metabolic function dysfunction. Growth curve assay showed that the pomegranate peel extract inhibited cytodieresis in logarithmic growth phase. After exposure to the pomegranate peel extract, bacterial protein was analyzed by SDS-PAGE. The results showed that protein synthesis was inhibited, especially for large molecular weight protein.
