This study investigates the impact of heavy metals on culturable rhizobacterial Pseudomonas fromhydrocarbon contaminated and ordinary soil. It deals with the isolation and characterization of culturable rhizobacterial from HC contaminated and normal soil also analyzed the influence of growth promoting efficiency of rice plant by Pseudomonas, Rhizobium. The heavy metal content of both soil samples were analyzed by AAS. Among the six heavy metals Calcium and Magnesiumwere found to be higher on both soils. Rhizobacterial strains isolated from hydrocarbon contaminatedsoil were more tolerant to heavy metals; the protein content was also higher when compared withrhizobacteria from normal soil. The Pseudomonas sp. from Hydrocarbon contaminated soil exhibitedbetter resistance to all the metals (Zn, Pb, Mn) than the normal soil, while the Rhizobium sp., showedmoderate resistance to the metal used on both soils. The representative PGPR strains of

Pseudomonas, Rhizobium from both soils are tested for plant growth promoting activities and heavymetal tolerance pattern. The study revealed the following criterion of the observation such as whenthe rhizobacterial strains were isolated from hydrocarbon contaminated soil showed enhanced plant growth promoting activity also increased protein content compared with normal soil isolatedrhizobacteria. Futhermore, Pseudomonas species from the normal soil proved the appearance of sharp phosphate solublization zone indicating this isolate was an efficient phosphate solubilizer thanthe normal soil. The results established that the hydrocarbon contaminated soil extractedPseudomonas sp., bacterium possessed a major role for stimulation of root and shoot growth as well as enhances the rice yield production from hydrocarbon contaminated soil.
