ΔsigB mutant utilizes glycerol inefficiently. L. monocytogenes wild-type strain 10403S (squares) and ΔsigB (triangles) cells were grown in defined medium supplemented with 0.4% (wt/vol) glycerol at 37°C. The curves are representative growth curves for the conditions investigated; all growth curve experiments were performed in triplicate. The inset shows the specific growth rates (SGR) derived from the curves. The errors bars indicate the standard deviations from the means of triplicate measurements. wt, wild type.
