TI  - Biodegradation of phthalate esters by two bacteria strains.
PG  - 533-8
AB  - In this study two aerobic phthalic acid ester (PAE) degrading bacteria strains, 
      DK4 and O18, were isolated from river sediment and petrochemical sludge, 
      respectively. The two strains were found to rapidly degrade PAE with shorter 
      alkyl-chains such diethyl phthalate (DEP), dipropyl phthalate (DPrP), di-n-butyl 
      phthalate (DBP), benzylbutyl phthalate (BBP) and diphenyl phthalate (DPP) are 
      very easily biodegraded, while PAE with longer alkyl-chains such as dicyclohexyl 
      phthalate (DCP) and dihexyl phthalate (DHP) and di-(2-ethylhexyl) phthalate 
      (DEHP) are poorly degraded. The degradation rates of the eight PAEs were higher 
      for strain DK4 than for strain O18. In the simultaneous presence of strains DK4 
      and O18, the degradation rates of the eight PAEs examined were enhanced. When the 
      eight PAEs were present simultaneously, degradation rates were also enhanced. We 
      also found that PAE degradation was delayed by the addition of nonylphenol or 
      selected polycyclic aromatic hydrocarbons (PAHs) at a concentration of 1 microg/g 
      in the sediment. The bacteria strains isolated, DK4 and O18, were identified as 
      Sphigomonas sp. and Corynebacterium sp., respectively.
