Figure 2

Comparison of growth rate coefficients in LB broth. The diagrams depict growth rate coefficients as estimated with the spline regression model between the different strains in interval 1, 2 and 3 cultured in LB broth with 0, 3 and 8 mg/ml (designated POSLB, 3LB, 8LB, respectively) lactoferrin added. The horizontal axes represent the different strains, while the growth rate, measured as change of OD per interval x 1000, is given on the vertical axes. Dashed horizontal lines represent 95% confidence intervals for each interval in each trial (i.e. POSLB, 3LB, 8LB). Growth rates, here represented as small bars, above the 95% confidence intervals were regarded as significantly higher compared to the growth rates within or below the dashed lines. Similarly, growth rates below the 95% confidence intervals were regarded as significantly lower than the growth rates within or above the dashed lines.
