AB  - The key step for anaerobic biodegradation of 2,4-dichlorophenol (2,4-DCP) is an 
      initial dechlorination reaction, but Cl in the para-position is more difficult to 
      remove than Cl in the ortho-position using normal 2,4-DCP-acclimated bacteria. In 
      this work, a bacterial community previously acclimated to biodegrading 2,4-DCP 
      slowly dechlorinated 4-chlorophenol (4-CP Cl only in the para-position), which 
      limited mineralization. That community was exposed to the selective pressure of 
      having 4-CP as its only organic substrate in order to generate a 
      4-CP-dechlorinating community. When the 4-CP-dechlorinating community was 
      challenged with 2,4-DCP, 4-CP hardly accumulated, although the kinetics for 
      2,4-DCP biodegradation were slower. When the community acclimated to 4-CP was 
      mixed with the community acclimated to 2,4-DCP, the 2,4-DCP removal rate remained 
      high, and 4-CP was more rapidly biodegraded. The genera Treponema, Blvii28, 
      Dechloromonas, Nitrospira, and Thauera were significantly more abundant in the 
      4-CP-dechlorinating biomass and may have played roles in 2,4-DCP dechlorination 
      and mineralization.
