The growth of Phaeocystis Globosa,total phosphorus in water,alkaline phosphatase activity in P.globosa cells were measured under different phosphorus conditions.When phosphorus deficiency and large molecular DOP(Lecithin)used in this experiment,alkaline phosphatase activity in P.globosa cells increased to 19.11U and 18.28U respectively,and both of them peaked at day 9.Results showed alkaline phosphatase played an important role in phosphorus deficiency stress and the utilization of large molecular of DOP.DIP(KH2PO4)and small molecular DOP(Natrium-β-glycerophosphat)can be easily utilized by P.globosa,whereas alkaline phosphatase activity did not changed significantly.
