Figure 8. Ethanol leads to higher levels of PCN crystal formation and 5MPCA derivatives.
A. P. aeruginosa strain PA14 wild type (WT) was grown on medium without and with 1% ethanol. With ethanol, PCN crystals form and the colony has a yellowish color likely attributed to reduced PCN. B. P. aeruginosa strain PA14 WT was cultured on lawns of C. albicans CAF2 (WT reference strain), the C. albicans adh1/adh1 mutant, and its complemented derivative (adh1/adh1+ADH1); the PA14 Δphz mutant defective in phenazine production was plated on the C. albicans CAF2 for comparison.
