AB  - A method for abatement for chlorophenols (CPs) in contaminated water based on 
      successive steps of catalytic hydrodechlorination (HDC) over Pd/C at ambient 
      temperature and pressure, followed by aerobic biodegradation using yeast Candida 
      tropicalis (C. tropicalis) was studied. The results showed that 4-chlorophenol 
      (4-CP) and 2,4-dichlorophenol (2,4-DCP) could be easily and completely 
      dechlorinated under mild conditions, ultimately yielding phenol as product. 
      Subsequently, phenol (0-900 mg L(-1)) could be completely degraded by C. 
      tropicalis within 30 h. Moreover, during the biodegradation of phenol, definite 
      mass of ethanol (</=0.5%) caused a modest increase in the duration of the lag 
      phase, but led to a great increase in the maximum degradation rates. This means 
      that CPs with higher concentration could be efficiently detoxified under mild 
      conditions by a combination of HDC and biodegradation in water or water-ethanol 
      systems.
