Growth of strains harboring H-NS mutants under acid stress. The change of OD600 of strains MG, Δhns, H-NS(WT) and strains harboring H-NS mutants cultured for 24 h in LBG medium with different initial pH values obtained by the addition of HCl: a pH 4.5 acidified by HCl, b pH 7.0 (not acidified), c pH 5.35 acidified by acetic acid and d pH 4.5 acidified by succinic acid. Error bars indicate the standard error of at least three biological replicates
