Time courses of dry cell weight (a), residual sugar concentration (b), the production of succinate (c), relative expression levels of sbtA, bicA, ppc and pck (a) and the specific activities of the PCK and PPC (e) under the expression of the HCO3− transporters in fed-batch fermentation. T The symbols for E. coli strains are the same as those in Fig. 2. Error bars show standard deviation (n = 3). Different letters (e.g., (a,b)) were assigned to significantly different groups and for the results between two groups.
