Abstract The oxidation of catechol, an intermediate in benzene catabolism, was studied using transient variations in dissolved oxygen tension (DOT) when a succinate limited steady state culture of Pseudomonas putida ML2 was perturbed with a pulse of another substrate. A model was developed and tested for the effect of fluctuations in oxidizing enzyme activity on DOT. It was found that the rate of induction of catechol o xidizing enzymes was independent of dilution rate up to a relative growth rate (μ/μmax) of 0.75. Only at higher dilution rates was catabolite repression observed.
