Solution

Bioreactors are vessels in which raw materials are biologically converted into specific products, using microbial, plant, animal or human cells or individual enzymes.
Role. A bioreactor provides the optimal conditions for achieving the desired product by providing optimum growth conditions (temperature, pH, substrate, salts, vitamins, oxygen). They aid in the production of desired products in large quantities. One of the most commonly used bioreactor is of stirring type.
