Figure 2From: Use of the lambda Red recombinase system to rapidly generate mutants in Pseudomonas aeruginosaΔ pqsC , Δ lasR and trpE-phnAB-Δ kynBU mutants do not produce pyocyanin. The production of pyocyanin, the P. aeruginosa blue phenazine pigment, is assessed in the mutants generated in this study after overnight growth in LB at 37°C.Back to article page
