Growth-curve (A) and expression analysis of three PAO1 fusion strains: PpsrA-lacZ (B), PrpoS-lacZ (C), and PexsC-lacZ (D). The growth rates were identical for all fusion strains and comparable to wildtype PAO1 strain. The expression of PsrA was induced (B) and the expression of ExsC was downregulated (D) by oleate in early-log and remained so for the entire log-phase. (C) The expression of rpoS decreased by the LCFA oleate as early as mid-log and lasted until stationary-phase, at which time the expression of rpoS in both media increased significantly.
