摘　　要：超氧化物歧化酶是生物体内一种重要的抗氧化酶,具有清除生物体内超氧阴离子自由基的作用,可有效地抗御氧自由基对有机体的伤害。概述水生生物(如鱼、虾、贝、藻)SOD的种类、分布、结构特征、理化性质及基因克隆表达的研究进展,并对其应用前景进行展望。Superoxide dismutase（SOD） is an important antioxidase in living creature, existing widely in cytoplasm, mitochondria and chloroplast of eukaryotic and prokaryotic cells, and it can efficiently eliminate superoxide free anion radicals in organism, and prevent organism damage from superoxide free anion radicals. This paper summarizes the research advances on hydrobios（ eg. fishes, shrimps, shellfishes and algaes ） superoxide dismutase in terms of types, distribution, structural characteristics, physicochemical properties and gene cloning and expression. Meanwhile, the prospect of its application is also forecasted.
