Fluoride (F) pollution is a worldwide problem, as there is no cure of fluorosis available yet. The strategies to remediate F contaminates in soils, phytoremediation approach using F accumulating plants is much convincing in terms of F removal efficiency. Plant Growth Promoting Rhizobacteria (PGPR) enhances the efficiency of phytoremediation. Two rhizobacterial strains Pseudomonas fluorescence (P.F) and Pseudomonas aeuroginosa (P.A) were used to determine the effects of inoculation on growth, antioxidant activity and the tolerance potential of Prosopis juliflora plants to accumulate F. These two strains, increases bioaccumulation factor (BF) 2.51-27.06 and translocation factor (TF) 0.66-1.10 of plant accumulated high amount of F in root. The organ wise accumulation showed an accumulation (15.9 mgkg-1 dw and 23.5 mgkg-1 dw) in shoot and root respectively. Further, increase of superoxide dismutase, catalase and peroxidase activity was also recorded. Pseudomonas fluorescence significantly increases the biomass and high bioaccumulation, translocation factor efficiency in comparison to Pseudomonas aeuroginosa. Present study suggests that the two PGPR strains could be used to improve the soil quality of F contaminated soil. Further enhances the efficiency of F hyperaccumulator plant P. juliflora for phytoremediation purpose.
