m-Cresol is one of the most abundant phenols in wastewater from hydrocarbon processing and coal conversion processes and at creosote-contaminated sites. The study of the anaerobic degradation of m-cresol has been hampered by the long acclimation time required to obtain active cultures as well as the difficulty of maintaining cultures. Fluorine can be introduced into a biologically active molecule to block metabolism, and fluorophenols are effective tools for studying phenol degradation. This study uses fluorinated analoges of phenol and m-cresol to help elucidate the pathway of m-cresol degradation under methanogenic conditions (anaerobic sewage sludge with a methanogenic m-cresol-degrading consortium). 49 refs., 7 figs.
