Figure 8From: The PhoBR two-component system regulates antibiotic biosynthesis in Serratia in response to phosphateA pstS mutant is largely unresponsive to P i limitation. (A) Pig and (B) AHL production was measured from a pstS mutant (ROP2) grown to early stationary phase in phosphate-limiting medium with (open bars) or without (solid bars) the addition of 5 mM KH2PO4.Back to article page
