ATCC k pneumoniae atcc baa 2473 strain
The 96-well microplate is filled with 100 μL of LB broth in columns 1–5 and 7–12. Subsequently, 100 μL of the AWME3 extract is added and serially diluted across columns 1–4 and 7–10. Next, 100 μL of the corresponding bacterial suspension is added to each well, with the exception of column 12, which is the blank. After incubation for 4 h, membrane permeability is evaluated by adding 10 μL of crystal violet solution to each well. The absorbance of the supernatant is measured at OD 570 nm after incubation in the dark for 15 min. All experimental conditions are performed in triplicate. Columns 5 and 11 serve as untreated controls, while column 12 (triplicate) is used as the blank. Numbers in the rows correspond to the tested K. pneumoniae strains: (1) KPi1627, (2) KPM9, and (3) K. pneumoniae ATCC <t>BAA-2473.</t>

(A, B) Kpi1627, KPM9, and KP ATCC BAA-2473 strains were cultured in LB broth and incubated overnight at 37 °C. Then, all strains were treated with 0.5 MIC (0.125 mg/mL) of AWME3, which did not show any turbidity and mucoviscosity. (C) Centrifugation for 10 min at low speed (1,000× g ) led to high precipitation of treated and untreated strains, and dense pellets were formed.
