Abstract：From the sediment of Taihu Lake,an efficient phosphate-solubilizing bacterial strain was isola-ted and the capacity was studied.With Ca3(PO4)2as phosphate source,traditional ten times gradient di-lution method with transparent circle combined was used for the functional strain screening,physiological characteristics and phylogenetic analysis of 16S rRNA gene were used for the taxonomic status determina-tion,molybdenum blue colorimetry was used for determination of the content of dissolved phosphorus.Re-sults showed that an efficient phosphate-solubilizing strain HXZ-21-Ⅲwas isolated and identified as Burk-holderia sp.,which had the phosphate-solubilizing capacity of 16.6 μmol/mL,negatively related to the pH value of circumstance. The strain distinctly stimulated the phosphate-solubilizing of soil and had a good application prospect.
