WebApr 7, 2024 · During the fermentations, the pH was set to 6.0 by the addition of either 2 M NaOH or a VFA mixture consisting of 150 g/L acetic acid (HAc) and 100 g/L propionic acid (HPr) (ratio HPr/HAc = 0.54 mol/mol), which simultaneously acted as a carbon source feed in a pH-stat fed-batch process. WebAlthough a single drop of 2 M HCl reduces the pH of 100 mL of water by 4 pH units (from 7 to 3), there is no change in the pH of the buffer when a drop of 2 M HCl is added to 100 mL of this buffer solution. Thus, the pH of the …
