ABSTRACT: Removal of heavy metals such as Cadmium, Chromium, Lead, and Nickel from wastewater was carried out through microorganism. For this purpose, heavy metals tolerant bacterial isolates were isolated from samples collected from Karnal, Panipat and Sonepat districts of Haryana using enrichment culture technique. The bacterial isolates tolerant up to 400 ppm concentration of heavy metals (Pb, Cd, Cr and Ni) were tested for removal of heavy metal from liquid media containing 50 ppm concentration of Pb, Cd, Cr and Ni each. The Maximum uptake capacity of Pb, Cd, Cr, Ni tolerant bacterial isolates (BPb11, BCd4, BCr24 and BNi12) were 55.88 mg/g, 2.42 mg/g, 4.29 mg/g and 5.39 mg/g respectively.
