Combination of quercetin and colistin contributes to the damage of bacterial cell membranes and the leakage of bacterial ALPs. The absorbance at 510 nm integrity of E. coli (A) and K. pneumoniae (B) by detecting ALP. The chart indicates that an increase for alkaline phosphatase in the medium after exposure to the specified compound. The results are shown as the mean and standard deviation of three independent experiments. ns stands for not significant, *p < 0.05, **p < 0.01, ***p < 0.001, determined by the Student’s t-test.
