Abstract:

A total of 60 endophytic actinomycete strains were obtained from root and leaf tissue of 30 banana trees. Each isolate was tested against phytopathogenic fungus Fusarium oxysporum. Thirty isolates (50%) were displaying antagonistic activity against Fusarium oxysporum, a pathogen of Panama disease. Out of 60 isolates, 41 belonged Streptomyces sp. (68.33%) followed by Nocardia sp. (11.7%), Micromonospora sp. (8.33%) and Saccharopolyspora sp. (5%) based on their morphological and culture characteristics. The extracellular chitinase activity of selected isolate i.e. BR9 came out to be 0.0115 and 0.065 U/ml with 0.6% and 1% colloidal chitin concentration respectively. This study revealed that endophytic actinomycetes isolated from banana roots and leaves tissue are potent natural sources and can be applied in agriculture.
