Abstract

Abstract

Fe²⁺/Vc system is used to generate hydroxyl radical.The proliferation of marine microalgae under hydroxyl radical stress is studied.The results indicate that the cell growth of microalgae is stimulated,the lipid peroxidation increases in the certain ranges and the activities of SOD of algal cells are enhanced under low concentration of hydroxyl radical stress.The growth of algal cell stimulated by ROS can be inhibited by antioxidant.Under high concentration of hydroxyl radical stress,the proliferation of algal cells is inhibited,the lipid peroxidation increases rapidly and the activities of SOD of cells declines.The antioxidant can alleviate the damage of algal cells under high concentration of hydroxyl radical stress.The sensitivities are different for different species of marine microalgae under ROS.stress.
