Cyanobacterial extracellular alkaline phosphatase:detection and ecological function

摘要

Dissolved inorganic phosphorus is an important form of directly bioavailable phosphorus for cyanobacteria in natural water.Dissolved organic phosphorus could be used by cyanobacteria via alkaline phosphatase,which is produced mainly by bacteria and also cyanobacteria itself.Herein,we review the current knowledge of extracellular phosphatase excreted by cyanobacteria,highlighting the development of detection method and its ecological roles in regulating pho sphorus cycling in freshwater systems,which is based on reports for around 100 species of cyanobacteria.Recommendations are suggested concerning the extracellular phosphatase produced by bloom-forming cyanobacteria in terms of the ecological role,followed by a discussion of the future prospects for the study.
