Question

Identify the part of a bio-reactor which is used as a foam braker from the given figure.

Options

• A

• B

• C

• D

Answer 1

D

Explanation:

The foam breaker is located at the top of the stirred-tank bioreactor schematic (C). It is a mechanical or chemical tool used to decrease or break up the froth produced during mixing or fermentation. Aerobic fermentation frequently produces foam due to gas bubbling and agitation, which can impede sensors and reduce performance. Foam breakers guarantee that there is no overflow or contamination and that the system runs properly.
