Activity of l-EP against E. coli K12 and the fepA mutant. (A) Representative phase-contrast and fluorescence micrographs of E. coli K12 and its outer membrane receptor mutant fepA treated with 15 µM l-EP in modified M9 medium for 11 h at 30 °C. Scale bar: 10 µm. (B) Quantification of the l-EP -induced bacterial morphologies in E. coli. (C) Viability of E. coli determined by LIVE/DEAD staining. For morphology and viability quantification, 500–1000 cells were manually counted for each condition from micrographs. For morphology quantification, cell size was measured and grouped by perimeter.
