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. | lld:pubmed |
