FIG 5.
Plate assay for rhamnolipids. SW agar plates were inoculated with hvKP1, hvKP1Δpeg-344, and a clinical isolate of Pseudomonas aeruginosa. The SW plates were incubated at 37°C for 48 h, followed by 4°C for 48 h. The precipitant around the bacterial colony identifies the presence of rhamnolipid.
