Fig. 2From: Synthetic acid stress-tolerance modules improve growth robustness and lysine productivity of industrial Escherichia coli in fermentation at low pHSchematic 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 24Â h in LBG at pH 5.0 (B). The OD600 was measured every 30Â min. Each experiment was performed in three biological replicatesBack to article page
