ROCCHETTA, Iara; RUIZ, Laura; CONFORTI, Visitación  and  RIOS DE MOLINA, María del Carmen. Estudio del estrés oxidativo en 2 cepas de Euglena gracilis. Rev Cubana Invest Bioméd [online]. 2003, vol.22, n.2, pp. 105-108. ISSN 1561-3011.

Studies of oxidative stress were conducted in 2 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.

Keywords : OXIDATIVE STRESS; EUGLENA GRACILIS; CHROMIUM; CLOROPHYLL.
