Question 31.1: The design of aeration systems for aerobic-fermentation proc...
The design of aeration systems for aerobic-fermentation processes is based on gas–liquid mass transfer. Microorganisms growin a liquid suspension and feed on dissolved nutrients such as glucose and mineral salts. Aerobic microorganisms in liquid suspension also require dissolved oxygen for growth. If oxygen is not supplied at a rate sufficient to support cell growth, the cells will die.
