Three bioreactor designs were used: stirred tank bioreactor (STB), bubble bioreactor (BB) and internal loop airlift bioreactor (ILAB). The bioreactors were evaluated for their influence on oxygen mass transfer coefficient (k L a), using various spargers, mixing speed, and aeration rates. Biomass and DHA production from STB, BB, ILAB were then ...

Jul 1, 2021The continuous stirred tank reactor is sometimes named a BMR or back-mixed flow reactor. Similar to a batch reactor, an agitator is intentionally added in a continuous stirred-tank reactor to fully disperse the reactants into a reaction compound immediately after they enter the tank. The product flow is continuously drawn off from the tank.

The key feature of single-use, stirred bioreactors is that their vessels are made of plastic. They are preassembled with an agitator, an oxygen delivery system, and single-use sensors, and are delivered by the vendor beta- or gamma-irradiated. After one-time use, the vessel and its installed components are discarded.
