Kinetics of bd oxidase expression. Expression of bd oxidase was measured every four hours. The expression system including both the constitutive plasmid (CP) and the positive feedback plasmid (PF) showed higher expression levels and faster expression kinetics than the controls. A logistic growth curve has been fitted to the readings. For the wild type (WT), the horizontal line represents the average expression of bd oxidase over the experimental interval, with the dotted lines enclosing the confidence interval for the mean.
