经对峙培养法测定，32个菌株对烟草青枯菌有拮抗作用，其中H-1、H-9和H-11有强拮抗作用，抑菌圈分别为3.0、3.0、4.5 mm。
根据其形态特征和生理生化性状，初步鉴定内生菌H-1为枯草芽孢杆菌，H-9和H-11为短芽孢杆菌。

Hunan Agricultural University, Changsha 410128, China)Abstract: One hundred and sixty endophytic bacteria strains were isolated from health tobacco plants in Guiyang county of Hunan province in disease severely infested plots. Thirty two, in particular three endophytic bacteria strains showed relatively strong antagonistic actions against Ralstonia solanacearum. Culturing these three bacteria and Ralstonia solanacearum together, the results showed that three endophytic bacteria H-1, H-9, and H-11 had the best antagonistic effects, and bacteriostasis diameters were 3.0, 3.0, and 4.5 mm, respectively. With regard to morphologic, physiological, and biochemical characterics, strain H-1, H-9, and H-11 were identified. The results showed that H-1 was Bacillus subtilis. H-9 and H-11 were Bacillus brevis. We also identified that they were all endophytic bacteria in tobacco.Keywords:ralstonia solanacearum; endophytic bacteria; colonization; identification烟草青枯病是由青枯劳尔氏菌(Ralstonia solanacearum)引起的一种以土壤传播为主的毁灭性细菌性病害。
