试验对筛选出的 6株具有明显促生防病作用的烟草根围细菌RB - 4 2 ,RB - 78,RB - 89,RB - 1,RB - 5 9,R2采用BioM啨ｒｉｅｕｘＡＴＢ系统进行了鉴定 ,结果可将RB - 4 2 ,RB - 78,RB - 89,RB - 5 9分别鉴定为Pseudomonasfluorescens - 1,Pseudomonasaeruginosa ,Pseudomonasfluorescens- 2 ,Enterobacterclocae。结合计算机测定和补充的生理生化特性测定结果 ,RB - 1,R2可分别鉴定为Enterobactergergoviae ,Agrobacteriumradibacter The results showed that 6 strains of RB - 4 2, RB - 78, RB - 89, RB - 1, RB - 5 9 and R2 were identified by BioM 啨 rieux ATB system. As a result, RB - 4 2, RB - 78, RB - 89 and RB - 5 9 were identified as Pseudomonas fluorescens 1, Pseudomonasaeruginosa, Pseudomonas fluorescens 2 and Enterobacter clocae. According to the results of physiological and biochemical characteristics measured and supplemented by computer, RB - 1 and R2 were identified as Enterobactergergoviae, Agrobacterium radibacter
