以芭蕉炭疽菌（Colletotrichum musae）为靶标菌,对内生细菌BYG2-5进行了皿内拮抗活性测定及感病香蕉活体组织控制作用测定.结果表明:该内生细菌有很好的皿内抑菌效果,抑菌带达到18 mm;内生细菌发酵液及滤液均能有效控制靶标菌在香蕉条上的扩展,特别是发酵液的病情控制率达到80.60％,防治效果明显.对...
The antagonistic activity of an endophytic bacterium BYG2-5 against Colletotrichum musae was studied on cultural medium.The results showed that strain BYG2-5 significantly inhibited the mycelial growth of C.musae with the inhibition zone reaching up to 18 mm.The fermentation fluid and its filtrate showed a high efficacy in suppression of infection caused by C.musae on banana fruits.Especially,treatment effect of the fermentation fluid was 80.6% against C.musae. The strain was identified as Bacillus litoralis based on its morphology,physiological biochemistry and 16S rDNA sequence.
