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. WebThe pH-Stat method increases arterial pCO 2 which leads to an increased cerebral blood flow and a loss of autoregulation which allows faster and more homogenous cooling and improved oxygen delivery, however it does permit an increased embolic load and may contribute to cerebral oedema during warming.
