The effects of inoculation of four chromate tolerant rhizobacterial strains previously isolated from rhizosphere of plants from chromium contaminated area in mung plant Vigna radiata grown on tannery sludge amended soil were evaluated. An increase of 138%, 88%, 256% and 54.14% in root length, shoot length, biomass and total chlorophyll, respectively was observed after 60 days of treatments by consortium. Similarly, a significant enhancement in Fe, Mn, Zn, Ni, Pb, Cr, Cu and Cd accumulation was observed in consortium inoculated plants as compared to non-inoculated plants. Results showed that rhizobacterial strain helps in ameliorating metal induced phytotoxicity, acquiring higher biomass and metal uptake in the plant may be useful in decontamination of metal from polluted soil.
