Figure 3. Modification of the rpoS mutant to constitutively produce surface lipoproteins doesn't alter its growth rate.

The parental clone 13A and transformants ΔrpoS/rpoS, ΔrpoS/ospC′ and ΔrpoS/C′B′A′ were cultured in BSK-H at 33°C. Cell numbers were determined once a day for 10 days under dark-field microscopy.
