Table 2.

Fluorophore uptake profile for three different membrane transporters of E. coli BW25113. Fluorescence (Signal Ratios) data are presented as the ratios of the fluorescence (median) from the three different E. coli knockout strains (∆yhjV, ∆yihN, and ∆tolC) over the fluorescence (median) from the reference strain ( E. coli BW25113). No difference between a KO strain and the reference would have had a ratio of 1. SD: standard deviation of the population, CI95: 95% confidence interval. The data for each knockout strain are sorted by incremental signal ratios
