一株铜绿假单胞菌的溶磷特征及其对底泥中Pb的固定化
Characteristics of Phosphate Solubilization of Pseudomonas aeruginosa and Its Immobilization of Pb in Sediment
摘要
Abstract
We studied the characteristics of phosphate solubilization of P seudomonas aeruginosa JM1 and its immobilization of Pb in sediment via pure culture and simulated experiment.The results show that strain JM1 is capable of dissolving Ca3 (PO 4 )2 and AlPO 4 which leads to the mass concentrations of dissolved PO 3 -4 are 240.63,92.73 mg/L,and pH in culture solution decreases to 4.64,5.12, respectively.Meanwhile,strain JM1 can grow on lecithin but not the release phosphations.Strain JM1 makes the mass ratio of immobilized Pb in the sterilized and without sterilized sediment increased to 14.02,1 1.83 mg/kg,which show that strain JM1 has strong ability to immobilize Pb in the sediment.关键词
