Özet
The biodegradation kinetics of o -cresol was examined by acclimatized P. putida DSM 548 (pJP4) in batch experiments at varying initial o -cresol concentrations (from 50 to 500 mg/L). The kinetic parameters of o -cresol aerobic biodegradation were estimated by using the Haldane substrate inhibition equation. The biodegradation kinetics of o- cresol was investigated. In batch culture reactors, the Maximum specific growth rate ( μ max ), Monod constant ( K s ) and the inhibition constant ( K i ) were established as 0.519 h -1 , 223.84 mg/L and 130.883 mg/L, respectively. o -cresol biodegradation in a batch-recirculation bioreactor system by immobilized P. putida was also studied. The recycled packed bed reactor system, which was composed of Ca-alginate beads and pumice on which cells immobilized, has been performed to determine possible stability for further developments.
