Figure 3

Flow cytometry histograms derived from scatter plots showing fluorescence of live (<103) or dead (>103) of L. innocua stained with PI post 24 h incubation with controls or extracts. X-axis corresponds to the PI positive marked microorganisms and Y-axis to the total cell count. (A) L. innocua sample PI negative control, 99.9% viability; (B) L. innocua incubated for 30 min with ethanol 70% PI positive control 46.4% viability; (C) water dry leaf non-boiled extract 4 μg/mL, 17.5% viability; (D) water non-dried leaves non-boiled 2.5 μg/mL, 16.7% viability; (E) ethanol 4 μg/mL, 28.5% viability; and (F) water dry leaf boiled 2 μg/mL, 25.6% viability.
