The aim of this study was to investigate the aerobic biodegradability of phenolic compounds characteristic to the oil-shale industry wastewaters--phenol, resorcinol and 5-methylresorcinol as both single and mixed substrates at different concentrations by the activated sludge of the Kohtla-Jarve WWTP and to obtain more information how these compounds influence each other's biodegradation.
