| Popis: | India is a largest producer of pomegranate with high export value. The cultivation is affected with the oily spot disease caused by Xanthomonas axonopodis pv. punicae infection. The present study aims to control the disease with newer biocontrol methods. Thirty-six isolates of X. axonopodis were isolated from different varieties of infected pomegranates fruits from Maharashtra. Forty strains of actinomycete were also isolated from natural sources and screened for their antagonistic activity against X. axonopodis isolates. Eight strains of actinomycete were screened out for their high antagonistic activity and were optimized for maximizing antibiotic production. The extracted compound from A5 strain exhibited maximum inhibitory activity against all the pathogenic isolates with a MIC in the range of 0.625 to 1.25 mg mL−1. It was identified as Streptomyces violaceusnige by 16SrRNA gene sequencing (Accession number KP208943). The extracted compound belonged to aminoglycosides with a molecular formula ... |
