Abstract: |
There are 15 strains of phosphorus-accumulating organisms were isolated from the soil of Phosphate Fertilizer Factory in HongHu. Among them, HS-P2 is one of the efficient phosphate accumulating organisms. Metachromatic granule staining displayed that poly-P granules exist in cells, and HS-P2 can be identified to Enterobacterspp according to morphological identification and 16SrDNA sequence alignment results. Under the aerobic condition, the curve of phosphorus dynamic showed that HS-P2 can remove the phosphorus to the maximum of 85% in the PO4 3- - P of 50mg / L medium at 48h, this study also showed that the optimal carbon source of HS-P2 is glucose, and the optimal pH is 7.0. It has a wide range of temperature for phosphorus removal of 30℃ to 37℃, which indicated that HS-P2 has a strong ability in phosphorus- accumulating,and a broad prospects in practical application.
