title: [Screening, identification and characterization of a quinclorac-degrading Arthrobacter sp. MC-10].
abstract: OBJECTIVE
  We screened and isolated bacterial strains from the perennial administration quinclorac paddy fields to degrade quinclorac.
  
  
  METHODS
  Strain MC-10, which can degrade quinclorac efficiently, was screened by enrichment and selective medium. The strain was identified by morphological, physio-biochemical characteristics and 16S rDNA gene sequence analysis.
  
  
  RESULTS
  MC-10 was identified as Arthrobacter sp. Under the optimal growth conditions with inoculum concentration of 5%, at 28 °C, pH 7 for 7 d, MC-10 degraded more than 90% of quinclorac. MC-10 can effectively degrade quinclorac when quinclorac initial concentration at 1 mg/L--100 mg/L. And the strain MC-10 has a good ability to survive in the soil. More than 70% quinclorac in the soil can be degraded efficiently after 7 days of cultivation.
  
  
  CONCLUSIONS
  Arthrobacter sp. MC-10 could be a promising microorganism in dealing with quinclorac pollution.
