Question

A bioreactor is:

• A. Culture for synthesis of new chemicals
• B. Culture containing radioactive isotopes
• C. Hybridoma
• D. Fermentation tank

Answer 1

The correct option is D

Fermentation tank

Bioreactors are large vessels with a capacity of 100 to 1000 litres, which are used for biological conversion of raw materials into specific products. Each bioreactor has a cylindrical stirred tank to facilitate the mixing of contents. It has an agitator system to mix the contents properly, an oxygen delivery system to make availability of oxygen, a foam control system, a temperature control system, a pH control system and a sampling port to withdraw small volumes of the culture periodically.
