Abstract:

Biodegradation of phenol with mixed consortia of bacterial was studied in an anaerobic batch reactor.The culture was acclimatized for a period of two months to grow in mineral salt medium contained phenol asthe sole carbon source. Minimum and maximum concentrations of 50 and 1000 mg/l of phenol in the mediumwere used for the purpose of culture adaptation. The goals of these experiments were to determine the kineticsof biodegradation by determination of biomass growth rates and phenol concentrations with respect toincubation time. Substrate inhibition kinetics and specific growth rate were defined while data were fitted inHaldane model. The specific growth rate, half-saturation and inhibition coefficients for Haldane model were0.067 hG1, 25.32 and 200 mg/l, respectively. The biokinetic parameters were used to predict the biodegradation profile, which was quite consistent with the obtained experimental data. The results were useful for the estimation of relations between growth rate and substrate utilization, which may be used to evaluate mass balance for a wastewater treatment plant contained phenol compound
