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

Question

Accepted Answer

B. 1. **Understand the requirement**: Industrial production of enzymes requires growing large volumes of microorganisms under carefully controlled conditions (temperature, pH, oxygen, nutrients) to maximize their yield.

2. **Identify the correct equipment**: A **bioreactor** is a vessel specifically designed to grow microorganisms (or cells) on a large scale under such controlled conditions, making it essential for industrial-scale enzyme and biomolecule production.

3. **Rule out the other options**: An **industrial oven** is used for heating/drying, not for growing living organisms; a **BOD incubator** is used in labs to measure biochemical oxygen demand of water samples, not for mass microbial culture; a **sludge digester** is part of sewage treatment, used to break down organic sludge, not to grow microbes for enzyme production.

Hence, the answer is **B. Bioreactor**.
