Abstract:
The alga, Chlorella, showed tolerance against Cd2 (10 µg/ml), and Ni+2 (12 µg/ml). Cadmium and nickel processing capability of alga was worked out. The reduction in the amount of Cd2+ after 7, 14, 21 and 28 days of culturing was 76%, 80%, 88% and 96%, respectively. Chlorella could also remove 78% Ni+2 after 7 days, 82% after 14 days, 88% after 21 days and 94% after 28 days from the medium. The resistance of alga against heavy metals present in industrial effluents indicates that the alga has acquired efficient means of resisting, tolerating or processing metal ions The heavy metal uptake ability of Chlorella can be exploited for metal detoxification and environmental clean-up operations.
