Abstract: Phytoremediation is an emerging technology that uses plants and their associated microbes to clean up pollutants from the soil, water, and air. In order to select the plant growth-promoting rhizobacteria (PGPR) for phytoremediation of heavy metal contamination soil.The present investigation was carried out in soil sample collected from Nallampalli, Dharmapuri district, TamilNadu. Bacterial PGPR isolates in agricultural soil. The PGPR bacteria identify Based on biochemical characterization and specialized literature were identified of the genus Pseudomonas and Bacillus in the soil. The sterilized soil was treated with 1% of Cu, Mn, Pb heavy metal by spraying. After Cu, Mn, Pb contaminated soil and agricultural soil were put in pots. Capsicum annum was selected to PGPR inoculated and metal inoculated on pots which significantly analyzing the plant biomass and photosynthetic pigments of chlorophyll, carbohydrates and Protein component was reported on inoculation microbes under heavy metal and determined the contaminated level in cultivated soil (inoculation Bioinoculants) compared to control plants at 45 DAI (Day After Inoculation). Bioinoculants inoculated plant’s fresh and dry weight were decreased under heavy metal treatment compared to microbes uninoculanted control plants. The results of this research showed that heavy metal metabolism was decrease in inoculation microbes on vegetable crops cultivated soil and heavy metal was degraded by microbes. Thus, the capacity of the microbes to survive and degrading of heavy metal and promoted to growth of vegetable crops on Bacillus spp. and Pseudomonas spp. were good candidates of environmental protector. Therefore, studying the behavior of heavy metal in the soil environment had great significance for its valid application. Phytostabilization is the process by which PGPR are stimulated to rapidly degrade the heavy metal contaminated soil to environmentally safe levels in soils.
