Question

What is a bioreactor? Explain important features of a stirred tank bioreactor.

Accepted Answer

A bioreactor is a large container or an apparatus in which living organisms such as microbes synthesise useful substances or break down harmful ones by various biological reactions. A bioreactor provides the optimal conditions by providing optimum temperature, pH, substrate, vitamins, oxygen, etc.

Commonly used bioreactors have a stirred tank bioreactor. The following are the important features of a stirred tank bioreactor:

It is usually cylindrical or with a curved base to facilitate the mixing of the reaction contents.

The stirrer facilitates even mixing and oxygen availability throughout the bioreactor.

It helps in better temperature and pH control.

It has a foam control system to prevent foam and shearing damage to cells due to agitation.

It has system sterilisation and provision to withdraw small volumes of cultures periodically.
