The accumulation of heavy metals in the ecosystem due to industrialization has led toxic effects on various life forms such as flora, fauna and microfauna. Several approaches that are currently used for removal not cost-effective efficient. Therefore, current study was focused bio-removal chromium (Cr), lead (Pb) zinc (Zn) using augmentation with strong biofilm forming Bacillus infantis (VITVJ8), which confirmed by augmented rhizosphere region Chrysopogon zizanioides a percentage 0.025%. bioremoval process catalyzed superoxide dismutase, chromate reductase catalase activity 83U/ml, 51U/ml 75U/ml, respectively. VITVJ8 also found be plant growth promoting bacterium it capable producing indole acetic acid (IAA) 63µg/ml siderophores 1.238cm solubilizing insoluble phosphate 72.3%. could tolerate Cr Zn up 1000ppm, whereas Pb 1250ppm. Further, rhizoremediation setup consisting C. strain showed enhanced uptake Zn, (89% > 86% 77%) compared phytoremediation (60% 62% 59%) treated plants. Seed germination assay revealed 75.78% increase index set-ups B. , reduction metal (HM) toxicity upon treatment effective growth. Since maximum roots versus shoots, vetiver can considered root accumulator Cr, when amended .
