E. coli CFT073 persistence in the presence of cPOS. Cultures were grown in 0.4% glucose M9 minimal medium as described in Methods and diluted 20-fold into 0.2% glucose M9 minimal medium either containing or lacking 1 mg/mL cPOS, and containing or lacking ampicillin (100 µg/mL). At 4 h and 24 h, the differences between E. coli CFT073 persisters in the presence of cPOS + ampicillin is significantly different than with ampicillin only (**P ≤ 0.01 and ***P ≤ 0.001, respectively). CFT073 cell viability with and without cPOS treatment were evaluated as controls.
