| Abstract: | In this paper,16 denitrifying phosphate-accumulating organisms(DNPAOs) were isolated in the special medium from the anaerobic/aerobic/anoxic SBR reactor,and the most efficient DNPAOs called Q-hrb05,was screened by a phosphate uptake experiment,where nitrates were denitrified to gas and through inspection of the poly-P.Strain Q-hrb05 was identified by 16S rDNA gene analysis,and the accession number of 16 S rDNA gene sequence of strain Q-hrb05 in GenBank was GU214826.The result showed that the strain Q-hrb05 belonged to Bacillus sp,of which the homology could reach to 99%,that also corresponded to the result of biochemical features.The average phosphorus uptake rate of strain Q-hrb05 was at 85% within 12 hours,and it had the denitrification capacity in the aerobic condition.It could be found that the phosphorus uptake rate was related to the content change of PHB.Under anaerobic condition,the maximal P-release rate was 66%,which could reach to 12% of the dry cell weight.The P-uptake rate was 92% with the decreasing of PHB content. |
