Ph stat method
WebWith the advent of rapid-responding pH and reference electrodes coupled to sensitive pH meters, these changes in H + ion concentration could be accurately measured. That measurement, which can be performed either directly or indirectly, forms the underlying principle upon which the electrometric methods for the assay of CA activity are built. WebMay 1, 2005 · A pH-stat feeding strategy was proposed to address the issue of glycerol oscillations that occur in repeated batch fermentations. This feeding strategy was based on direct coupling of growth and concomitant production of H+ and this led to a constant minimum concentration of glycerol (main C-source) in the induction period.
