Industrial effluents consist many pollutant and heavy metals. Bacteria isolated from industrial west water ground may have potential to tolerate heavy metal. In this study we isolate a Citrobacter sp. which can resist heavy metal like Cu and Pb. Slurry from industrial west water ground was collected from 22.0663 N, 88.1041 E. The heavy metal content and other parameters of soil were estimated. ...
