Question

Which of the following statements is incorrect?

• A. A bio-reactor provides optimal growth conditions for achieving the desired product
• B. Most commonly used bio-reactors are of stirring type
• C. Bio-reactors are used to produce small scale bacterial cultures
• D. Bio-reactors have an agitator system, an oxygen delivery system foam control system

Answer 1

The Correct Option is C

Bio-reactors and Their Use:

Bio-reactors are primarily used for large-scale production of microbial cultures, not small-scale. They provide optimal growth conditions by regulating factors like temperature, pH, and oxygen levels to enhance the production of desired products such as antibiotics, enzymes, and biofuels.

Thus, the correct answer is (3)

Bio-reactors are used for large-scale bacterial cultures.
