四尾栅藻对重金属镉胁迫的响应
Effect of Cadmium on Scenedesmus quadricauda
摘要
Abstract
Heavy metal pollution is one of the most concerned water environmental problems. In this study, the effects of different Cd2+con-centrations on the growth, pigments, hydrogen peroxide, superoxide anion and soluble protein of Scenedesmus quadricauda were investigated in laboratory. Result showed that algal growth was inhibited under cadmium stress, especially under high cadmium concentrations(3~7 mg· L-1). Pigment(chlorophyll a, chlorophyll b, and carotenoids)contents decreased with increasing concentrations of cadmium. Contents of hy-drogen peroxide and superoxide anion increased significantly under 5~7 mg·L-1 and 7 mg·L-1, respectively. Soluble protein content reached the maximum at 1 mg·L-1 and decreased afterwards. Scenedesmus quadricauda displayed better tolerance to cadmium(upto 1 mg·L-1 cad-mium).关键词
