Question

Which of the following condition is not maintained in a Bioreactor for optimum growth condition?

• A. Temperature
• B. Vitamin
• C. Salts
• D. None of the above

Hint:

Bioreactors maintain conditions like temperature, pH, oxygen supply, and salts, but vitamins are usually not externally regulated.

Answer 1

The Correct Option is B

Step 1: Understanding bioreactors.
A bioreactor is a vessel that provides an optimum environment for the growth of microorganisms or cells in large-scale culture. It maintains physical and chemical conditions like temperature, pH, oxygen supply, and essential nutrients.

Step 2: Analysis of options.
- (A) Temperature: Controlled in bioreactors for proper microbial or cell growth.
- (B) Vitamin: Not specifically maintained in bioreactors; microbes can synthesize many vitamins themselves.
- (C) Salts: Required to maintain osmotic balance and nutrient availability, hence controlled.
- (D) None of the above: Incorrect, because vitamins are not directly maintained.

Step 3: Conclusion.
The correct answer is (B) Vitamin, as vitamins are not specifically maintained in bioreactors.
