Average growth, GFP expression and rhamnose secretion in WT cells. A) Average growth of WT cells (black) with standard deviation (gray), inoculated at 0.0025 OD600 over three independent experiments. Average GFP expression (in arbitrary units), under the control of the PA01 rhlAB-promoter (green) with the standard deviation (light green) constructed from the same experiments. B) Time series of rhamnose secretion in WT from three independent experiments (grayscale squares). The time series were constructed using the calculated time-shifts from the respective experiments. For each rhamnose measurement, the median is plotted with the entire range of the measurements represented as error bars.
