(A) Viable cell counts (CFU/mL) from P. aeruginosa PAO1 48 hr static cultures in None-SCFM2, PGM-SCFM2, and BSM-SCFM2. PGM-SCFM2 and BSM-SCFM2 contain 5 mg/mL crude mucin. (B) Fold change secondary metabolite levels produced by PAO1 in PGM- and BSM-SCFM2 compared to None-SCFM2. PGM: porcine gastric mucin; BSM: bovine submaxiliary mucin; PHZs: phenazines; AQs: alkyl quinolones; RLs: rhamnolipids; PCH: pyochelin; PVDs: pyoverdines. Corresponding abundance of individual metabolites is in Figure S1. One-way ANOVA (n = 4 biological replicates per condition). * p ≤ 0.05; ** p ≤ 0.01; *** p ≤ 0.001; **** p ≤ 0.0001
