Abstract：Using the medium with Ca3 (PO4)2 as the sole phosphorus source to screen the phosphate solubilizing ability isolates of Penicillium strains which were stored in laboratory..In order to obtain the strains with the highest phosphate-solubilizing capacity,the first selected Penicillium strains were individually inoculated into the liquid medium containing Ca3 (PO4)2 as the sole phosphorus source to quantitatively analyze their phosphate solubilizing ability.The results showed that the QM-10 strain had the highest ability of phosphorus solution.With the increase of incubation time,the soluble phosphorus content increased firstly,then decreased and finally tended to stabilize.After 96 hours of concussion culture,the soluble phosphorus content in the culture solution of QM-10 was the highest as 1 386.93 mg/L.The pH value of its culture solution first decreased and then tended to be stable,corresponding to the minimum value as 2.29.The morphological and molecular identification confirmed that QM-10 strain belonged to Penicillium oxalicum.
