Isolation and Molecular Characterization of Plant Growth Promoting Rhizobacteria from Groundnut (Arachis Hypogaea L.) Rhizosphere

Plant growth promoting rhizobacteria (PGPR) have been extensively employed as biofertilizers to enhance the soil nutrition for several crop plants. Rhizobacteria with beneficial effects plants could therefore be used reduce dependence on synthetic chemical fertilizers in conventional agriculture. Within this study, we explored isolation of potential PGPR groundnut from agricultural fields Saurashtra region, Gujarat. A total forty-two isolates rhizospheric different colony characteristics were isolated. All strains tested plant (PGP) traits observe their properties and all isolates. such indole acetic acid (IAA), hydrogen cyanide (HCN), ammonia production, phosphate solubilisation gibberellins production performed. Thirty-four produced IAA range 20.7–133 µg/mL, seventeen positive 21.4–55.5 twenty-six HCN 5.65–114.3 µg/mL,4isolates displayed 65.6–259.5 5 10.2–112.1 µg/mL. Moreover, only RGKP3 RG12 results PGP traits. The potent isolate was further identified using 16SrRNA sequencing. strain has close evolutionary similarities Priestia megaterium. In future will studied promote growth, enhanced a biofertilizer.
