Abstract

In this study the effect different concentration of heavy metal cadmium (0, 5, 10 and 20 μ M) on two microalgea, Anabaena sp. were examined. After cadmium treatment, all samples with three replication were transferred to culture room with temperature of 28± 1 ° C, light intensity of 2500 lux and duration of 16 hours light and 8 hours darkness with aeration condition. The results showed that with increasing cadmium concentration up to 20μ M in microalgea Anabaena sp. The content of pigments (chorophyll a, β-carotene, phycobiliproteins) and total protein were significantly reduced compare to control. Malondialdehyde (MDA) content as a product of oxidative stress and Enzyme activity of peroxidase (POD), ascorbate peroxidase (APX) and superoxid desmutase (SOD) significantly increased. According to the results, microalgae Anabaena sp. in short-term stress of metal cadmium low concentrations used in this study are sensitive.
