ABSTRACT

 

Extensive screening was carried out for the novel actinomycetes with diverse metabolic potential with respect to multiple plant growth promotion activities. The isolation was carried out by direct as well as by enrichment methods. Total 52 isolates were obtained from 10 samples using four different selective medium. Primary screening of these isolates were carried out for multiple PGPR and antimicrobial activities. Results showed that nine potential actinomycetes isolates which were further screened for their quantitative abilities. Actinomycetes isolate C13 was also found to produce hydrolytic enzymes such as amylase (0.08 EU), lipase (0.026 EU), protease (12.12 EU), cellulase (1.08 EU), chitinase (0.002 EU). It was found to show antibacterial activity against S. aureus and antifungal activity against T. viridae and F. oxysporium. Beside this, it was also found to show potential PGPR activities such as siderophore production of 36.83 % IAA production 9 mg/l and phosphate solubilization atributes.
