Comparative assessment of heavy metal removal by immobilized and dead bacterial cells: A biosorption approach
Microorganisms play a vital role in heavy metal contaminated soil and wastewater by the mechanisms of
biosorption. In this study, heavy metal resistant bacteria were isolated from an electroplating industrial effluent samples that uses copper, cadmium and lead for plating. These isolates were characterized to evaluate their applicability for heavy metal removal from industrial wastewaters. The physico-chemical parameters of the samples were initially analyzed. The optimum conditions of pH, biomass concentration and heavy metal concentration were determined for the microbial growth on biosorbents and correlated with heavy metal removal. The observed optimum conditions were applied for the biosorption process carried out in immobilized and dead bacterial isolates. The biosorption of immobilized cells of
Bacillus sp. was 69.34% of Cu, Pseudomonas sp. was 90.41% of Cd and Micrococcus sp. was 84.27% of
Pb, whereas the dead cells of Bacillus sp. was 44.73% of Cu, Pseudomonas sp. was 86.66% of Cd and Micrococcus sp. was 79.22%. Experimental results reveal that all the immobilized isolates have potential application for the removal of Cu, Cd and Pb from industrial wastewater than the dead bacterial cells
