摘要：

Three bacterial strains were isolated from industrial effluents of Penang, Malaysia. The strains RZ1, RZ2, and RZ3 were identified as Pantoea sp. RL32.2, Salmonella enterica, and Enterobacter sp. OCPSB1, respectively, based on morphological observation, biochemical, physiological characterization, and 16S rDNA sequence analysis. The strains RZ1, RZ2, and RZ3 removed 89.89, 82.10, and 89.14% of cadmium, respectively, when the 100g/mL of cadmium was added in the medium. The minimum inhibitory concentrations of strains RZ1, RZ2, and RZ3 were 750, 410, and 550g/mL, respectively. Cured strain showed resistance and sensitivity against some range of antibiotics. The molecular weights of induced proteins were 35 and 25kDa in the presence of cadmium which points out a possible role of this protein in cadmium removal. Overall, these strains could be useful for the removal of cadmium in industrial wastewater.
