Figure 6From: The PhoBR two-component system regulates antibiotic biosynthesis in Serratia in response to phosphateP i limitation affects secondary metabolism and QS. (A) Pig and (B) AHL production in WT cells were measured throughout growth in phosphate-limiting medium with (squares) or without (triangles) the addition of 5 mM KH2PO4. In all graphs, solid lines represent Pig or AHL assays and dashed lines represent bacterial growth.Back to article page
