title: [Research on the isolation of denitrifying bacteria from domestic wastewater and its capability of removing nutrient salt from eutrophic water body].
abstract: OBJECTIVE
  A kind of bacteria associated with highly denitrifying capability was isolated, and investigated about its growth and degradation characteristics.
  
  
  METHODS
  By using an enrichment culture and plate dilution method, one strain of bacteria was isolated from domestic wastewater and their denitrifying capability on the river water received domestic wastewater was determined.
  
  
  RESULTS
  The isolated bacteria strain had some nitrogen and phosphorous removal ability, its denitrifying intensity was 63.2%. The efficiencies of removing TN (total nitrogen) and TP (total phosphorus) (76.2% and 93.8%, respectively) were the highest when the consortium was added at the dosing amount of 100 mg/L after treatment for 10 days.
  
  
  CONCLUSIONS
  One strain of denitrifying bacteria was successfully isolated from sewage sediments; its removal capacity of nitrogen and phosphorus from eutrophic water was good, which provided a basic biological method for nitrogen and phosphorus removal associated with eutrophic sewage treatment.
