Antibiofilm and Antioxidant Activity of Propolis and Bud Poplar Resins versus Pseudomonas aeruginosa

Figure 2

Growth curve of Pseudomonas aeruginosa P1242 in presence of propolis and bud poplar resins extracts. P. aeruginosa cells were grown in presence or absence of extracts at 10, 50, and 100 μg/mL for 24 h at 37°C. Gentamicin (1.8 μg/mL) was used as positive control. Luminescence of live cells in the culture is expressed as relative luminescence units (RLU).
