%X 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 (¦Ìmax), monod constant (ks) and the inhibition constant (ki) 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.
