Abstract

Chlorella vulgaris beijernick was grown in medium BG-11 with 5 concentrations of copper (10, 20, 30, 40, 50 M) without ALUMINUM or with ALUMINUM (300 M) and pH 7.1 for 10 days in 20 hours light and 4 hours darkness. In this study, the effect of different treatments on the activity of peroxidase, catalase, Ascorbat peroxidase and superoxid dismotase and NITRATE REDUCTASE, in vivo, was evaluated. Increase of copper concentration caused increase in activity of ANTIOXIDANT ENZYMES. Catalase activity in the presence of ALUMINUM in all copper treatments showed a significant reduction, but peroxidase and Ascorbat peroxidase activities in 20mM treatments decreased significantly when compared with control. The significant decrease in the activity of catalase, peroxidase and Ascorbat peroxidase activity, in 20 mM copper with ALUMINUM comparing with 20 mM copper without ALUMINUM was also observed. Results also showed that the effect of different concentrations of copper without ALUMINUM on NITRATE REDUCTASE activity was not significant and most NITRATE REDUCTASE activity in treatments with copper and ALUMINUM was observed in 40 mM that was significant when compared with 20mM treatment and was not significant when compared with other treatments or control. It is concluded that the presence of ALUMINUM, by increasing some of ANTIOXIDANT ENZYMES activities, lead to reduce of COPPER TOXICITY and algae growth increases.
