Identification of a High Phosphate-accumulating Organisms and Study of Its Poly-phosphate Characteristics
(0) 15 bacterial strains with a capacity of poly-phosphate were isolated from enrichment culture of the soil sample collected from the phosphate fertilizer factory of Honghu City in Hubei province, of which one strain named as HS-P7 has the strongest effects of poly-phosphate. Ammonium molybdate spectrophotometric method was used to measure its ability of poly-phosphate. The results showed that phosphorus removal rate about the strain HS-P7 reached to 90.08% when it was cultivated in the phosphorus-rich medium in 30℃ during 72 hours. The homology between the strain HS-P7 and Pseudomonas cf. Monteilii is 98% by comparing their 16S rDNA. Based on the characteristics of morphological, physiological and biochemical, the strain HS-P7 was identified as Pseudomonas sp. The effects of different temperatures, pH, carbon sources and nitrogen sources on the growth of the strain HS-P7 were investigated and the optimum growth condition was determined as pH 7.0 and 30℃.
