Figure 9. The RsmA mutant is able to grow aerobically on citric acid.

Wild-type (wt), rsmA⁻, and rsmB⁻ strains were tested for their ability to grow aerobically in minimal medium containing 0.2% citric acid as the sole carbon source. The absorbance of cultures at 580 nm was recorded up to 27 h post inoculation. Experiments were performed in triplicate.
