Fig. 1From: Synthetic acid stress-tolerance modules improve growth robustness and lysine productivity of industrial Escherichia coli in fermentation at low pHRelative strengths of the synthetic asr promoter library entries, compared to the wild type asr promoter. The black dots represent the pH response ratio of the fluorescence signals obtained in LBG medium at two different pH (pH 5.0 vs pH 7.0). Each experiment was performed in three biological replicatesBack to article page
