Often aerobatic fermentations give off CO 2 gas because the respiring cells produce CO 2 as glucose
Question:
Often aerobatic fermentations give off CO2 gas because the respiring cells produce CO2 as glucose nutrient is converted to chemical energy. The conditions used to set kLa for O2 transfer in the fermenter also establish the same hydrodynamic conditions for CO2 transfer. Consequently, the transfer rate of CO2 from the liquid to the aeration gas is also described by this volumetric mass-transfer coefficient, kLa. Consider that the kLa for O2 in the fermenter is 300 hr1. Scale the kLa for O2 to kLa for CO2 transfer using film theory, boundary-layer theory, and penetration theory, and compare the results.
