Activity against E. coli, P. aeruginosa, and L. monocytogenes. Radial diffusion assays were performed in underlay gels that contained different amounts of NaCl (0 mM, 100 mM, or 200 mM), in addition to their common basic ingredients (10 mM sodium phosphate buffer, pH 7.4; Trypticase soy broth powder, 0.3 mg/ml; and 1% [wt/vol] agarose).
