Question

Sodium carboxy methyl cellulose is not a type of non-nutritional media supplements.

(a) True

(b) False

I got this question in quiz.

This question is from Medium Optimization in chapter Introduction to Fermentation Processes & Media for Industrial Fermentation of Bioprocess Engineering

Answer 1

The correct answer is:

(a) True

Explanation:

Sodium carboxymethyl cellulose (CMC) is not considered a non-nutritional media supplement. Instead, CMC is a type of nutritional supplement that can be added to media for specific purposes such as acting as a carbon source or aiding in the growth of certain microorganisms.

• Non-nutritional media supplements typically include substances like antifoaming agents, pH buffers, or antibiotics, which do not provide direct nutritional value to the microorganism but help in managing the fermentation environment or controlling microbial growth.
• Sodium carboxymethyl cellulose (CMC), on the other hand, can serve as a carbon source or as a stabilizing agent in certain media, making it a nutritional supplement.

Therefore, the statement that CMC is not a type of non-nutritional media supplement is true, since it serves a different role in media formulation compared to non-nutritional supplements.
