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

ABSTRACT: To search endophytic bacteria diversity and evaluate their antibacterial activity, healthy medicinal plant of Scrophularia striata was chosen in this study. One hundred endophytic bacteria were isolated from surface-sterilized tissues (root, stem and leaf) of S. striata. Using sequence analysis targeting 16S rRNA gene, eight genera, including Agrococcus, Arthrobacter, Bacillus, Chryseobacterium, Delftia, Kocuria, Pseudomonas and Sphingomonas 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 Bacillus cereus, 17(54.8
