Phenazine production in PA23, PA23-443, and PA23-443 harboring ptrA in trans. Panel A. Color development of overnight cultures grown in M9 minimal media supplemented with 1 mm MgSO4 and 0.2% glucose. Left to right; PA23 (pUCP22), PA23-443 (pUCP22), PA23-443 (ptrA-pUCP22). Panel B. Quantitative phenazine analysis of cells grown in M9 minimal media supplemented with 1 mm MgSO4 and 0.2% glucose. Horizontal lines; PA23 (pUCP22), vertical lines; PA23-443 (pUCP22), diagonal lines; PA23-443 (ptrA-pUCP22). Total phenazine: phenazine-1-carboxylic acid + 2-hydroxy-phenazine. *; P < 0.0001, **; p < 0.0002.
