Diversity and antibacterial activity of endophytic bacteria associated with medicinal plant, .

To search endophytic bacteria diversity and evaluate their antibacterial activity, healthy medicinal plant of was chosen in this study. One hundred endophytic bacteria were isolated from surface-sterilized tissues (root, stem and leaf) of . Using sequence analysis targeting 16S rRNA gene, eight genera, including , , , , , , and were identified. Antibacterial activity of endophytic bacteria was examined against some test bacteria, employing agar well diffusion method. Out of 31 endophytic bacterial isolates, 24(77.42%) isolates showed significant antimicrobial activity against , 17(54.84%) isolates exhibited maximum activity against , 14(45.16%) isolates against and 5(16.13%) isolates showed positive activity against .The results obtained in this study suggested that the medicinal plant, is is a potent source of endophytic bacteria with antibacterial activity and offers promise for discovery of more impressive biological compounds.
