摘    要:实验研究磷酸二氢钠、β-甘油磷酸钠(Na-β-glycerophosphat,NaGly)、磷酸钙和卵磷脂(lecithin ,LEC) 4种不同形态的磷源对铜绿微囊藻的生长代谢及其与附生假单胞菌磷代谢关系的影响.测定了微囊藻的生长,水中磷浓度的变化,碱性磷酸酶活性(alkalinephosphataseactivity ,APA)和微囊藻中总磷含量的变化.结果表明,附生假单胞菌的存在能促进铜绿微囊藻的生长,并可以将微囊藻不易直接吸收的磷形态转化为磷酸盐等物质供微囊藻利用.碱性磷酸酶在微囊藻和X菌利用大分子有机磷的过程中起重要作用.

关 键 词:铜绿微囊藻  假单胞菌  磷形态  碱性磷酸酶

Abstract: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.
Keywords:Microcystis aeruginosa  Pseudomonas sp    phosphorus forms  alkaline phosphatase
