Effect of Al antioxidiant enzymes activity,nitratereductase activity, amount of osmolite and release of ammonium in Dunaliella salina teodoresco
Aluminum effect with 0, 100, 200, 300, 400, 500 and 1000 µ molar concentrations was considered during ten days on Dunaliella salina teodoresco antioxidant enzymes, smolit contents,nitrate reductase activity and ammonium release on were measured. The results showed that ammonium release, peroxidase , nitrate reductase activity and glycinebetaine content had not any significant differences but catalase,superoxide dismutase(300 µmolar concentration) activities,and prolin content decreased and ascorbate peroxidase activity increased significantly.Based on the results of this study, the green alga Dunaliella salina teodoresco green alga can tolerate Al stress by ascorbate peroxidase activity increase.
