what is the advantage of a sparged bioreactor over simple stirred bioreactor?
A bioreactor is essentially a vessel in which raw materials are biologically converted into specific products by efficient control of conditions like pH, Temperature, substrates, salts, oxygen etc. It provides optimal conditions to obtain a desired product.
A simple stirred bioreactor is cylindrical with a curved base to help in mixing of contents inside the reactor. There is a stirrer which mixes the contents evenly and supplies oxygen uniformly all over.
In a sparged bioreactor the vessel is broader and flat from the bottom. Oxygen is bubbled into the system. Bubbles increase the oxygen transfer area and the shape provides increased surface area for oxygen transfer.
