Which one of the following equipments is essentially required for growing microbes on a large scale, for industrial production of enzymes?
Answer: (D) Bioreactor. Answer: (D) Bioreactor Solution: Large-scale (100-1000 litres) culturing of microbes for industrial production of enzymes, vaccines and other biotechnological products requires bioreactors, vessels providing optimum growth conditions (temperature, pH, substrate, oxygen).
- A.BOD incubator
- B.Sludge digester
- C.Industrial oven
- D.Bioreactor✓
Correct Answer
(D) Bioreactor
Solution & Explanation
Answer: (D) Bioreactor Solution: Large-scale (100-1000 litres) culturing of microbes for industrial production of enzymes, vaccines and other biotechnological products requires bioreactors, vessels providing optimum growth conditions (temperature, pH, substrate, oxygen). Small-volume cultures cannot yield appreciable quantities, so bioreactors were developed for large-scale production.
