A study of biosorption of cobalt metal by Pseudomonas Aerguinosa gram-negative bacterial strain is presented. The present study is carried out to determine the optimum conditions of cobalt biosorption at ultra-low concentration (ppb range) in aqueous solutions. The receptiveness of cobalt metal on the extracellular surface of bacterial strain was examined by varying the pH, Initial concentration of metal and treatment time. Experimental data showed that effect of pH and treatment time is prevalent in biosorption of cobalt and by increasing both these parameters resulted in the efficient sorption of cobalt on the extracellular surface of Pseudomonas Aerguinosa. In some cases, higher initial concentration of cobalt resulted in higher metal removal. However, there is no clear relationship is obtained between efficiency of biosorption and initial concentration of cobalt.
