Root colonising bacteria (rhizobacteria) that exert beneficial effects on plant development via direct or indirect mechanisms have been defined as plant growth promoting rhizobacteria (PGPR). PGPRs have the potential not only to enhance plant growth, but also to boost soil fertility considerably. Thirteen bacteria were isolated from the rhizospheric soil of Jatropha growing in degraded soil under semiarid conditions from southern India. Preliminary pot trials were carried out to investigate the interaction of these isolates with seeds of the test plant Jatropha curcas. Based on the preliminary results [Pot trials, Gram’s-nature, Catalase test (qualitative test) and qualitative phosphate solubilisation], six strains were identified employing 16s rRNA techniques. Further, phosphate solubilisation activity, indole acetic acid, siderophore, exo-polysaccharide, ammonia, catalase and HCN were characterised by in vitro experiments.
