Bioremediation of tannery effluent by Enterococcus casseliflavus

🔖 A bacterial strain was isolated from tannery effluent which showed the chromium resistant activity and was identified as Enterococcus casseliflavus. The Enterococcus casseliflavus showed very high level chromium resistance of 800 µg/ml by agar dilution method. The minimal inhibitory concentration of chromium was found to be 512 µg/ml of potassium dichromate in nutrient broth medium. The chromium uptake was significantly high in live pellet cells than killed pellet cells at 540 nm in different time intervals. Reduction of chromium was not prominently found. Removal of chromium by Enterococcus casseliflavus In tannery effluents was observed.
