Abstract

Cr(VI) at 2. 5, 5, 7. 5 and 10mg/l was removed over 1-5 days by a freshwater cyanobacterium, Chroococcus sp. 2. 5mg Cr(VI)/l gave the optimum rate. With 5mg Cr(VI)/l, activities of superoxide dismutase and catalase were increased. Amounts of palmitic (16:0), stearic (18:0) and oleic acid (18:1) in the cell also increased after exposure to Cr(VI).
