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

Answer 1

The correct option is D

Bioreactor

The correct option is D.

The explanation for the correct option :

1. Enzymes are types of proteins, which has great economic importance due to their use in various industries like food, cosmetic, agriculture, pharmaceutical, etc.
2. They are derived from microbes for large-scale production in industries by different processes like fermentation.
3. Bioreactors are the large vessels used to produce microorganisms in a biologically controlled environment.
4. It is used to grow enzymatic microbes in industries.

The explanation for the incorrect option:

Option A:
BOD (Biological oxygen demand) incubator is an instrument used to maintain the temperature in Tissue culture and store bacterial cultures.

Option B:
A sludge digester is an instrument used to decompose organic solid sludge into simpler substances.

Option C:
Industrial ovens are used for drying, curing, or baking purposes.

Final answer: Bioreactor is essentially required for growing microbes on a large scale for industrial production of enzymes.
