| Abstract: | Twenty two endophytic bacterial strains were isolated from the healthy tissues of banana, of which 1 strain named BEB9 was screened and showed inhibitory activities against races 1 and 4 of Fusarium oxysporum f sp cubense. This strain was identified as Burkholderia based on its morphological, physiological, and biochemical characteristics and the 16S rDNA sequences analysis, and NA and YE cultural media were optimum for antagonistic culture of this strain. |

| Keywords: | banana endophytic bacteria Burkholderia. |
