Question

Which one of the following equipments is essentially required for growing microbes on a large scale, for industrial production of enzymes?

• A. BOD incubator
• B. Sludge digester
• C. Industrial oven
• D. Bioreactor

Answer 1

The Correct Option is D

To solve this question, we need to identify which equipment is crucial for the industrial-scale growth of microbes, particularly for enzyme production. Each option will be evaluated based on its function and relevance to the question:

1. BOD Incubator:

   A BOD (Biological Oxygen Demand) incubator is primarily used for incubating samples at a constant temperature to assess the oxygen demand of microorganisms in water. It is more related to environmental testing rather than industrial-scale microbial growth.

2. Sludge Digester:

   Sludge digesters are used in waste treatment processes to break down organic matter. They are not primarily designed for enzyme production or cultivating microbes for industrial purposes.

3. Industrial Oven:

   An industrial oven is utilized for high-temperature processes such as baking or drying. It is not suitable for growing microbes since microbial cultivation requires controlled environments like humidity and temperature that industrial ovens cannot provide.

4. Bioreactor:

   A bioreactor is a vessel in which biological reactions take place. It provides a controlled environment to maximize the growth of microbes and is specifically designed for large-scale production of biological products such as enzymes, vaccines, or antibodies. The conditions such as temperature, pH, and oxygen supply can be tightly controlled, making it ideal for this purpose.

Conclusion: The most suitable equipment for growing microbes on a large scale for industrial enzyme production is a Bioreactor. This equipment allows for the precise control of environmental conditions necessary for optimal microbial growth, making it the correct choice.

Thus, the correct answer is Bioreactor.
