摘要：

Addition of powdered activated carbon to a continuous-flow activated-sludge culture in a gas-lift bioreactor growing on o-cresol in a mineral-salts medium resulted in a reduction of the effluent o-cresol concentration during steady-state conditions as well as during shock-load conditions. During the latter conditions the activated carbon acted as a buffer. Bioregeneration of loaded activated carbon did occur, resulting in enhanced biodegradation of o-cresol. Adsorption of o-cresol by activated carbon was not sufficient to explain the total difference in effluent o-cresol concentration between the system with activated carbon and the system without activated carbon.
