Soil pollution by the heavy metals is one of the most significant environmental problems and has its negative impact on human health, agriculture and needs to be remediated by biological approach. Biosorption is a process that utilizes inexpensive biomass to sequester toxic heavy metal, which is mediated by Extracellular and Intracellular sequestration. This approach is particularly useful for the removal of contaminants from landfill site. The aim of this study was to screen the bacterial isolates for their potency to accumulate heavy metal (Cu2 +). Bacterial isolates (n=49) were isolated from soil collected from different zone of Bhanpur landfill area, Bhopal (M.P.) and screened for their capacity to tolerate in the presence of different concentration (100 to 700 µg/ml) of Cu2+ . All the isolates showed tolerance against Cu2+ ( 100 µg/ml). However the most promising results appeared in isolates CRSY3 and CRSY4. The strain were identified as on the basis of morphological and biochemical characterization Bacillus sp and Pseudomonas sp. In addition, bioaccumulation potential of bacterial isolates and their consortium were also determined by atomic absorption spectrophotometer (AAS). The capability of bacteria’s alone or consortia (Bacillus sp + Pseudomonas sp) displayed maximum accumulation (51.2%) after 72 hrs compared to both cultures. The study revealed metal accumulating bacteria with metal removal ability which could further be utilized as a potential tool for detoxification of the polluted sites.
