Fig. 3From: Quercus infectoria gall extracts reduce quorum sensing-controlled virulence factors production and biofilm formation in Pseudomonas aeruginosa recovered from burn woundsa Quantitative measurement of biofilm inhibition in P. aeruginosa by crystal violet staining and measuring absorbance at 490 nm. Data are presented as mean ± SE. b Crystal violet stained light microscopic images of bacterial biofilms grown in the absence and presence of SICs of Q. infectoria gall extracts. c untreated, Q-1: ethyl acetate, Q-2: n-butanol, Q-3: ethanol, Q-4: aqueous extractBack to article page
