Relative fold change of bamA expression in the mutant strains (light gray) relative to the WT strain (dark gray) using quantitative real-time RT-PCR analysis. Quantification of bamA RNA transcripts was performed in triplicate, and the expression of E. coli 16S rRNA genes was used as a reference to normalize the results for each strain. The fold change is shown on a logarithmic scale. *, P > 0.01 (significant differences from the WT). The error bars indicate standard deviations.
