Abstract:

Gram-negative bacteria like Pseudomonas are well reported to play a significant role in detoxification of various heavy metals like cadmium. The possible way to remove cadmium from the environment is to immobilize the metal within the system. Pseudomonas stutzeri MTCC 101, a highly cadmium tolerant strain harbors a mega plasmid (~15kb) which is likely responsible for such metal tolerance. However MTCC 101 showed conspicuous morphological abnormalities as revealed by SEM-EDX analysis. Focus was given to determine the biosorption potential of the organism. Optimization of biosorption potential of MTCC 101 showed that the mid log phase cells could accumulate maximum Cd2+ at neutral pH when cell-metal mixtures were incubated for about 30 hr at 37°C. MTCC 101 produces profuse EPS under metal stress which is likely to contribute to biosorption potential of the organism. Hence, the metal sorption potential of P. stutzeri could be effectively utilized in the bioremediation of cadmium.
