Effects of VOCs on the growth of A. fumigatus. (A) Quantitation of A. fumigatus (Af) biomass in the presence of 100 ppm of pure VOCs identified in the P. aeruginosa culture headspace. Only DMS significantly increased growth, and only 2-nonanone had a significant inhibitory effect. (B) Comparison of the growth-promoting effects of 1 ppm DMS (DMS1) and 10 ppm DMS (DMS10) on sulfur-replete MM and on sulfur-deficient MM (MM-S). CTRL, control. (C) Residual concentration of DMS in the culture headspace of the double-plate setup. DMS produced by P. aeruginosa (grown on MM) or the pure compound (1 and 10 ppm) is partially consumed by the A. fumigatus fungus when grown on MM (Af) but is fully consumed on sulfur-deficient MM [Af(-S)]. (D) Agar plates showing the growth stimulation of A. fumigatus by DMS. As shown in panel B, the effect is increased when the fungus is grown under sulfur starvation. All error bars show the SEM of the mean values. Values that are significantly different are indicated as follows: *, P ≤ 0.05; †, P ≤ 0.05; **, P ≤ 0.01.
