Advances in researches of aquatic ectoenzyme and its relationship with red tide
海水中胞外酶及其与赤潮发生关系研究进展

Ectoenzymes play an important role in the material cycle and energy conversion in aquatic ecosystem. The researches of ectoenzyme are of significance in further understanding the marine carbon biogeochemical cycle and the countermeasures of algae under bloom conditions.In this paper, the research methods, characteristic activity and size distribution, controlling factors and their ecological significances of algal ectoenzymes were reviewed, and ectoenzyme introduced as one kind of new trophic state index.
