Schematic diagram and cell growth of the modules for the strains overexpressing gadE, hdeB, sodB, katE or katE-sodB. Schematic diagram (A). Cell growth of E. coli strains overexpressing gadE, hdeB, sodB, katE, or katE-sodB under the control of different asr variants and wild type E. coli MG1655 (WT) cultured for 24 h in LBG at pH 5.0 (B). The OD600 was measured every 30 min. Each experiment was performed in three biological replicates
