Abstract
Heavy metal–resistant bacterial strains were isolated from heavy metal–contaminated soils and identified as Bacillus sp. and Leclercia adecarboxylata on the basis of their morphology and biochemical characters using the VITEK 2 Systems Version 05.02. The heavy metal and antibiotic resistance of the isolates were studied. A green house pot experiment was conducted to examine the bacterial ability to extract the lead in soils and for their effect on lead uptake by Ricinus communis in an artificially contaminated soil. Bacterial inoculated pots increased the biomass of the R. communis compared to the uninoculated control, and the root growth of the plant was also increased in the inoculated pot. The experimental data confirmed that lead‐resistant bacteria have a pronounced effect on heavy metal uptake in plants, which may provide a new bacterially assisted phytoremediation of metal‐contaminated soils. © 2013 Wiley Periodicals, Inc.
