| 摘 要： | 从全国各地棉田采集土样，筛选对棉花黄萎病致病菌大丽轮枝菌（Verticillium dahliae Kleb.）具有拮抗作用的芽孢杆菌菌株。通过初筛得到具有拮抗作用的菌株68株，复筛选出1株拮抗活性较高的菌株7-47，并通过生理生化试验，形态特征的观察及16S rDNA的序列分析对其进行了鉴定，认为菌株7-47属于漠海威芽孢杆菌（Bacillus mojavensis）。

| Abstract: | We had isolated 68 strains which have antagonistic activities against Verticillium dahliae Kleb.from the soil in cotton fields via preliminary screening.From them,a strain named 7-47 with a relatively higher antagonistic activity was obtained via secondary screening.The strain 7-47 was characterized by physiological and biochemical experiments,morphological features observation,and 16S rDNA sequence analysis.Based on the results,the strain 7-47 was finally identified as a kind of Bacillus mojavensis. |
