Q. Aeration and agitation function synergistically to maximize the volumetric mass transfer coefficient (k_La) while maintaining homogeneous mixing. Consider the following statements regarding their respective roles:

P: Sparging introduces gas into the liquid to supply O2 and strip out metabolic CO2, thereby providing the necessary gas holdup (ε).

Q: Agitation relies on low-shear hydrofoil impellers to decrease the bubble residence time, ensuring rapid gas turnover in high-density cultures.

R: The mechanical action of impellers serves to thin the liquid film resistance (k_L), which facilitates better mass transfer across the gas-liquid interface.

S: The synergistic effect of aeration and agitation is primarily aimed at minimizing the specific interfacial area (a) to prevent foaming.
