Biosorption can be an effective technique for the treatment of heavy metal bearing waste water resulting from human and industrial activities. Several Gram positive and negative bacteria have the ability to remove the heavy metals, thereby making water contaminant free. The present work has been designed to test the efficiency of the bacterium in the removal of cadmium from aqueous solutions. Experiments were also designed to study the effect of sugars on the biosorption of cadmium ions. Pseudomonas oleovorans MTCC 617 procured from IMTECH, Chandigarh was used in the present study. The tolerance of the strain for cadmium was found out by plating onto Nutrient agar containing different concentrations of cadmium. P. oleovorans was exposed to different concentrations of cadmium (250, 500, 750 and 1000 ppm) for a period of eight days. Dead cells of P. oleovorans were also employed to study the biosorption of cadmium. AAS analysis was carried out for the sample at intervals of two days. Highest cadmium removal was found to be at 750 ppm concentration for ten minutes with dead cells of P. oleovorans.
