In the current study, a sum of eight bacteria were confined from the rhizospheric soil of Capsicum annuum gathered from various areas of Gangyada Vikarabad, Telangana, India and were characterized for multiple plant growth promoting (PGP) ability, lytic enzyme synthesis and antagonistic activity in vitro. Four of eight bacterial isolates showed the production of indole acetic acid in the range of 22.4±0.57 to 120.3±0.64 µg/ml, three isolates exhibited phosphate solubilization in the range of 60.6±1.63 to 294.1±1.18µg/ml. Furthermore out of eight bacterial isolates, two isolates were capable to produce siderophore and HCN and effectively restricted the mycelial development of Sclerotium rolfsii and Macrophomina phaseolina in dual culture assay. Two bacterial isolates viz., RM-1 and RM-2 exhibited most PGP traits, hydrolytic enzyme production and antagonistic activity were further identified at molecular level by 16S rRNA gene sequencing analysis as Pseudomonas sp. and Bacillus cereus. These findings firmly suggest that the PGP bacteria recognized in this study can be valuable for development of effective biofertilizers/bio-inoculants to improve growth and productivity of Capsicum annuum.
