The most important bioreactor for industrial applications is the conventional stirred tank reactor (STR), due to its high flexibility and low operating costs. Bioreactor purchases are often subjected to more scrutiny and debate than many other items of equipment of similar complexity and cost. The choice and sheer number of different systems can seem daunting. This article throws light upon the 4 major types of STR bioreactors used in bioprocess technology.
