Ground water contaminated with creosote or oil contains a mixture of phenols and monoaromatic hydrocarbons. The possibility for anaerobic biodegradation of mixtures of these contaminates is of interest. The biodegradation of phenol and cresols has been shown to occur under different anaerobic redox conditions. In mixtures of aromatic hydrocarbons, partial degradation of o-xylene has been observed concommitant with the degradation of toluene, while no loss of o-xylene occurred with out toluene metabolism. This study further investigates the toluene-dependent degradation of o-cresol. On the basis of the experimental data, a mathematical model describing the kinetics of o-cresol degradation was developed and the kinetic parameters of the process were estimated. 35 refs., 3 figs., 1 tab.
