    Variations in pH affect the growth and recombinant protein production. The effects of the pH variation in cultures carried out at a controlled pH (7.5 ± 0.1) and uncontrolled pH on biomass growth, total protein and rSMD yields were evaluated (Figure 1).By controlling the external pH at 7.5 ± 0.1, the cytoplasmic pH is maintained in the same range simulating the physiological E. coli
