Δms strain failed to grow on acetate as a sole carbon source : overnight grown cultures of WT and Δms strains of S. Typhimurium were diluted in LB broth (A) or M9 media supplemented with either 0.4% glucose (B) or 0.4% acetate (C) and grown on a shaker incubator. The aliquots were taken at an interval of 1 h and optical densities were measured at 600 nm. Data is presented as mean ± SD (n = 3).
