Do other factors such as pH, agitator speed, etc. affect system response?
Factors such as pH (3-9), agitator speed (100-1200 rpm), air sparge rate, supplemental oxygen addition rate and antifoam addition do not have an effect on the system’s response or stability, therefore allowing trouble free control of methanol concentration throughout the fermentation. This is critical when using varying air flow, agitator speed and on-demand supplemental oxygen addition to control the dissolved oxygen level.
