Abstract

Abstract

Alkaline phosphatase activity(APA) and dissolved phosphonis were monitored during the batch cultures of two marine microalgae.Results indicate that variation of APA was in the shape of "S" curve.Different species of dissolved phosphorus had different effects on APA.The concentrations of dissolved inorganic phosphorus(DIP) and small molecular dissolved organic phosphorus(SDOP) had a significant effect on APA,while the concentration of large molecular dissolved organic phosphorus(LDOP) had a little effect on APA.,and the increase of APA could accelerate the decotrtposing of LDOP in the medium.Results also show that algae species and abundance had only a little effect on APA.
