  • a Ratios of the mutant to the wild type in an in vitro growth competition experiment at different times. Strains were grown BB10 with shaking under microaerobic conditions. The wild-type strains are isogenic with the corresponding mutants. Each competition assay was repeated two times, and similar results were obtained. The results for one replicate for each mutant are shown.
