Growth of single-gene knockout strains. Bacteria were grown at 37°C for 9 h in LB. Samples were taken every 30 min and the OD of appropriate dilutions was determined at 600 nm. (A) Comparison of growth of the parent strain Ye wildtype, all mutant strains Ye ΔbamB, ΔbamC, ΔbamE, ΔdegP, ΔsurA and Δskp and the complemented mutants Ye ΔbamB-pACYC, ΔsurA-pACYC and Δskp-pACYC. (B) Growth curves of Ye wildtype strain, ΔbamB strain and ΔbamB strain carrying wildtype BamB on a plasmid (ΔbamB-pACYC).
