Question

A typical bioreactor has

a. An agitator system
b. An oxygen delivery system
c. A foam control system
d. A temperature control system
e. A pH control system
f. Sampling ports

• A. $a,b,b,d$ and $e$
• B. $a,b,c,d,e$ and $f$
• C. $a,b,c$ and $d$
• D. $a,b$ and $c$

Answer 1

The correct option is B $a,b,c,d,e$ and $f$

Bioreactors are large cylindrical vessels that are used for large scale culturing of cells (plant, animal or microbial cells) to obtain specific gene products for commercial use. It provides optimum conditions, such as temperature, pH, nutrients, oxygen (aerobic bioreactors) etc., for the optimum growth of cells.

A bioreactor consists of the following parts:

• An agitator system to stir the culture well.
• An oxygen delivery system to supply sterile air.
• A foam control system to break the foam regularly.
• A temperature control system to maintain the suitable temperature for the growth of culture.
• A pH control system to maintain the suitable pH for the growth of culture.
• Sampling ports to withdraw small volumes of the culture

Hence the correct option is
d. a, b, c, d, e and f
