FIG. 5.

Growth on maltodextrins and cyclodextrin (CD). Relative growth of KKV884 cells expressing WT or mutant OmpU porins in the presence of 1 mM of the test sugar: maltotetraose (T4), maltohexaose (H6), or CD. The values are expressed as the ratio of the A₆₀₀ value after 24 h of growth in minimal medium containing 1 mM of the test sugar to the value after growth in the presence of 1 mM glucose. A value close to 1 (dashed line) indicates that the growth is comparable to that in glucose. The histogram bars and error bars show the averages ± standard errors of the means of the results from three independent colonies.
