title: Oxidative stress response and fatty acid changes associated with bioaccumulation of chromium [Cr(VI)] by a fresh water cyanobacterium Chroococcus sp.
abstract: Cr(VI) at 2.5, 5, 7.5 and 10 mg/l was removed over 1-5 days by a freshwater cyanobacterium, Chroococcus sp. 2.5 mg Cr(VI)/l gave the optimum rate. With 5 mg 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).
