Abstract

The pollution of the environment with toxic heavy metals is spreading throughout the world along with industrial progress. Microorganism and microbial products can be highly efficient bio-accumulators of soluble and particulate forms of metals especially dilute external solution. Microbe related technologies may provide an alternative or addition to conventional method or metal recovery. The present study deals with isolation, identification and characterization of heavy metals resistant bacteria were isolated from roots Eichhornia crassipes in emerging pollutant drainage sites of industries at Unnao, Gajraulla, Hindon River Ghaziabad and Sobhapur village NH-58 Meerut. The eighteen bacterial strains were authentically identified as Pseudomonas aeruginosa, Pseudomonas fluoresencs, Escherichia coli, Micrococcus luteus, Kleibsella pneumonaie, Staphylococcus aureus, and Bacillus subtilis. The isolates showed optimum growth at alkaline pH 6.5 to 8.5 and optimum temperature for 37.0°C to 4.5°C. The identified isolates are resistant to Arsenic trioxide (As2O3), Chromium tri-oxides (Cr2O3), Cadmium di oxides (CdO), Lead oxides (PbO), Zinc oxides (ZnO), Nickel oxides (NiO) and Copper Oxide (CuO). The identified heavy metals resistant bacteria could be useful for the bio remediation of heavy metal contaminated industrial effluent and waste water.
