An Evaluation of the Antibacterial Properties of Tormentic Acid Congener and Extracts From Callistemon viminalis on Selected ESKAPE Pathogens and Effects on Biofilm Formation

Figure 4

The effect of exposing P aeruginosa to ciprofloxacin (0.016 µg/ml) and tormentic acid congener (100 µg/ml) on release of intracellular protein in P. aeruginosa. The absorbance intensities of treated P aeruginosa cells were measured at 590 nm. Results are presented as mean (n = 3) ± standard deviations. Asterisk denotes a significant difference (^∗∗P < 0.01).
