The effects of different forms of phosphorus sources on the phosphorus metabolism of Microcystis aeruginosa and attached Pseudomonas sp. were investigated after four substance of different phosphrus forms: NaH2PO4, Natrium-beta-glycerophosphate (NaGly), Ca3(PO4)2 and lecithin were added in the non-phosphorus MA culture. The growth of Microcystis aeruginosa, total phosphorus, alkaline phosphatase activity in water and total phosphorus in Microcystis aeruginosa were measured every day or every two days. Results show that attached Pseudomonas sp. could accelerate the growth of Microcystis aeruginosa, and transform some phosphrus forms which could not be assimilated very easily by Microcystis aeruginosa to some forms as phosphate to utilize for Microcystis aeruginosa. Alkaline phosphatase plays an important role in the utilization of large molecular organic phosphorus by Microcystis aeruginosa and attached Pseudomonas sp.
