Effects of porin mutations on susceptibility to β-lactams and SDS.
Strains were grown in LB to ~0.4 of OD600. Culture densities were normalized, 10-fold serial dilution were prepared for each and 5 μl of each dilution was spotted onto LB without or with an chemical agent as indicated. ∆double represents a strain lacking both major porins. Results shown are representative of three independent experiments.
