Effects of fluorinated analogues on transformation of phenol to benzoate by an anaerobic, phenol-degrading consortium were examined. At concentrations of > or = to 250 microM, 2- and 3-fluorophenol inhibited transformation of phenol as seen by a lag in its disappearance. Benzoate accumulated in the presence of > or = to 250 microM 3-fluorophenol. In contrast, 4-fluorophenol had no significant effect on either phenol transformation or benzoate accumulation when present to 2 mM. Phenol and 2-, or 3-fluorophenol were transformed simultaneously, but phenol was transformed more rapidly than either fluorophenol. 2-Fluorophenol was converted to 3-fluorobenzoate in the presence or absence of phenol; however, the presence of phenol enhanced the rate and extent of its transformation.
