%X An acclimated activated sludge was examined for its ability to degrade 3-fluorophenol in aerobic batch cultures.The result indicated that the organism degrades up to 100 mg/L 3-fluorophenol completely with approximately 100% fluoride anion release within 16 h.3-Fluorophenol can serve as the sole carbon source and energy source for the organism.The acclimated activated sludge can degrade 3-fluorophenol effectively.The degradation mechanism study reveal that the initial step in the aerobic biodegradation of 3-fluorophenol is its transformation to fluorocatechol.Following transformation of the fluorophenol to fluorocatechol,ring cleavage by catechol 1,2-dioxygenase proceedes via an ortho-cleavage pathway,then defluorination occurres.
