Question

Which Substrate is consumed rapidly in fermentation process?

(a) Fructose

(b) Glucose

(c) Sucrose

(d) Lactose

I have been asked this question in final exam.

This is a very interesting question from Oxygen Uptake in Cell Cultures in section Mass Transfer of Bioprocess Engineering

Answer 1

(b) Glucose

Glucose is typically consumed rapidly in fermentation processes compared to other substrates like fructose, sucrose, or lactose. It is the preferred energy source for most microorganisms, as it is easily metabolized and utilized in glycolysis to produce energy (ATP), which supports cellular growth and metabolic activities during fermentation.
