Fig. (6) Analysis of role of trp genes in LSMMG phenotypes. S. Typhimurium  and E.coli Δ trpR and Δ trpDE strains were compared to respective WT strains for LSMMG-mediated alteration of acid and oxidative stress as described in Figs. (3, 4). The data was obtained from at least three independent experiments each plated in triplicate, and the average and standard deviation are plotted. The differences between LSMMG and control were significant at p-value < 0.05.
