Which one of the following instruments is useful for the production of microbes on a large scale?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Fermentors
Microbes are used to make many useful products, such as beverages, antibiotics, organic acids and enzymes. Making them on an industrial scale needs the microbes to be grown in very large vessels called fermentors.
(1) Evaporators — Incorrect. Evaporators remove water from a liquid. They are not used to grow microbes.
(2) Fermentors — Correct. Microbes are grown in fermentors on a large scale.
(3) Fumigators — Incorrect. Fumigators spread fumes to kill pests. They do the opposite of growing living things.
(4) Refrigerators — Incorrect. Refrigerators keep things cold, which slows the growth of microbes.
