| Popis: | The response of pure cultures of Escherichia coli, Candida parapsilosis, and bacterial virus f2 to ultraviolet light radiation was studied in a batch reactor and in a completely mixed, flow-through annular reactor. Two kinetic models were tested as to their ability to scale between batch results and flow-through reactor results. Using the respective best-fit kinetic parameters for each model from batch data, the response of the organisms in the flow-through reactor could be predicted by using either multi-target kinetics or series-event kinetics. The series-event model was judged to be superior to multi-target kinetics because it better represents the known mechanism of u.v. inactivation than does multi-target kinetics. Since two different models can be used to describe the data, the simple agreement between experimental data and model predictions does not necessarily prove that either model is mechanistically correct. |
