Question

Assertion A: Microbial growth is increased when agitation speed rises.
Reason R: Oxygen mass transfer improves but shear damage to cell also occurs.
In the light of the above statements, choose the most appropriate answer:

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

In bioprocessing, agitation is a balancing act. You want enough speed to "feed" the cells oxygen, but not so much that you "crush" them with shear forces.

Answer 1

The Correct Option is B
