Question

Difference between simple stirred tank and sparged stirred tank bioreactor

Answer 1

A stirred tank reactor is usually cylindrical or with a curved base to facilitate the mixing of the reactor contents.

Stirrer facilitates even mixing and oxygen availability throughout the bioreactor.

Alternatively air can be bubbled through the reactor.

The difference between the simple stirred and the Sparged stirred is that :

Bubbles increase the oxygen transfer area in Sparged whereas there is absence of oxygen bubbles in Simple stirred.
