摘要
从生姜田土中分离到一株对姜瘟青枯劳尔氏菌(Ralstonia solanacarum)有强拮抗作用的泛菌菌株Q6,对该菌株进行了形态特征、培养特征、生理生化特征的鉴定及16S rDNA序列的分析.以16S rDNA序列为基础构建了包括12株相关种属细菌在内的系统发育树,其中与11个泛菌属的菌株的16S rDNA序列的同源性为95.54%～99%.
Pantoea Q6 was isolated from the soil of ginger in Bazhong against ginger bacterial wilt causedby Ralstonia solanacarum. It＇s morphological, cultural physiological, biochemical characteristics and 16S rDNA sequences analysis were studied. A phylogenetic tree was constructed by comparing with the published 16S rDNA sequences of the related bacteria species. In the phylogenetic tree the overall similarity value between strain Q6 and 11 type Pantoea are 95.54 % - 99 %.
