Influence of synthetic acid-tolerance modules on lysine production in 1.3-L parallel bioreactors. The lysine titers (A), lysine yields (B) and OD600 (C) of E. coli MG1655 SCEcL3 harboring different synthetic acid-tolerance modules and the parent strain E. coli MG1655 SCEcL3 cultured for 48 h in an industrial fermentation medium maintained at pH 6.8 or pH 6.0. The graph shows the results at 48 h. Each experiment was performed in three biological replicates. * Represents significance (p < 0.05). ** represents significance (p < 0.01)
