Abstract
Experiments are reported in which a mixed population of organisms was continuous cultured on phenol in a 1β to 2βliter wellβmixed vessel. Steady state phenol concentrations were measured for a range of inlet concentrations from 100 to 800 mg/liter at various dilution rates. These results were compared with those predicted from a model which incorporates the effect of wall growth. It was found that the effect of growth on the walls of the vessel was considerable and increased by a factor of up to 3 Γ the dilution rate at which 90% conversion of phenol could be obtained.
