Studies of oxidative stress were conducted in two strains of Euglena gracilis (MAT and UTEX). The cultures were subjected to different concentrations of hexavalent chromium. The superoxide dismutase activity, the amount of total lipids and the concentration of clorophyll were determined and the respective growth curves were obtained. The results obtained show that chromium besides affecting the production of lipids, clorophyll and cellular growth, increases the superoxide dismutase activity. Significant differences are observed between both strains.
