Phenol Degradation Performance in Batch and Continuous Reactors with Immobilized Cells of Pseudomonas putida

Phenol is a highly persistent environmental pollutant and toxic to living organisms. The main objective of this study observe the phenol degradation performance by free immobilized Pseudomonas putida (P. putida) in batch continuous reactors, respectively. Batch experiments were evaluated determine maximum specific growth rate, saturation constant, inhibition cell yield. These kinetic parameters used as input values for continuous-flow cells model. model was validated experimental results obtained from an reactor. model-predicted showed good agreement effluent concentration mode. In steady-state condition, high removal achieved under various hydraulic retention times. corresponding ranged 93.3 95.9%, while times maintained at 3.1–10.5 h. Furthermore, polyvinyl alcohol-immobilized with nanoscale particles also prepared. P. Fe3O4 enhanced ability degradation. revealed that nano-Fe3O4 had highest low salinity 1%. However, advantage addition insignificant higher 5%. approaches column tests practical treatment actual phenol-containing wastewater.
