Figure 1. Effects of RsmA on PCA production and the growth of strain M18 and its mutants.

Figure 1

Growth curves (open symbols) and PCA production (solid symbols) were determined for (A) the wild-type strain M18 (squares) and its rsmA mutant M18ΔRA (triangles), (B) M18ΔRA/p-rsmA (squares) and M18ΔRA/pME6000 (triangles), (C) triple-mutant M18ΔMSP1 (squares) and quadruple-mutant M18ΔMSAP1 (triangles), and (D) triple-mutant M18ΔMSP2 (squares) and quadruple-mutant M18ΔMSAP2 (triangles) in PPM broth at 28°C. M18ΔRA/pME6000 indicates rsmA mutant M18ΔRA harbouring an empty pME6000 plasmid. M18ΔRA/p-rsmA indicates rsmA mutant M18ΔRA harbouring recombinant pME6000 that expressed the rsmA gene. Values are the means ± standard deviations of triplicate cultures.
