The rhizosphere is the zone of soil around the roots in which microbial biomass is directly impacted by the presence of roots. A beneficial rhizobacteria community is essential for growth and development of the plant host. In the present study, total 7 different samples were collected from different sites and total 19 bacterial isolates were obtained from different soil samples. All isolates were screened for different enzyme activities i.e. cellulase, amylase, protease, lipase, pectinase, chitinase. 16 isolates were positive for cellulase, 16 isolates were positive for amylase, 15 isolates were positive for protease, 14 isolates were positive for lipase, 18 isolates were positive for pectinase and 18 isolates were positive for chitinase. Isolates were also characterized for plant growth promoting activities like IAA, phosphate solubilization, nitrogen fixation, ammonia production, catalase, zinc solubilisation, seed germination and pot assay. 10 isolates were positive for IAA, 18 isolates were positive for phosphate solubilization, 17 isolates were positive for nitrogen fixation, 12 isolates were positive for ammonia production, many isolates gave promising result for seed germination and pot assay. Isolates were also checked for biocontrol activities such as HCN production and antimicrobial activity. 5 isolates were positive for HCN production, one isolate gave positive result for antibacterial activity and one isolate gave positive result for antifungal activity. Looking to overall activities together isolates B5 and B9 were found more efficient for all the activities under study.
