In this study, phenol-degrading microorganisms were isolated from an activated sludge system that had been acclimated with synthetic phenolic wastewater for six months. After investigating the performance of each strain on phenol, in the presence and absence of co-substrate, the best-isolated strain was chosen. In the next phase, the best-isolated microorganism's growth on different phenol concentrations was examined in a shaking flask scale, at different times. The kinetic constants obtained by modeling the growth kinetic of the best isolated strain, according to the Haldane model, and with the help of Matlab 6.5, were µm=0.592 (1/h), Ks= 920.3 (mg/L), and KI= 115.62 (mg/L). This kinetic model is a good tool for simulation and scale-up in designing an industrial wastewater bio-treatment process.
