Statement I : Bioreactors are designed to process large volumes of culture, typically ranging from 100 to 1000 litres.

Statement II : The main function of a bioreactor is to store culture media without providing any control over growth conditions.

Only statement I is correct.

The correct answer is Option (1) - Only statement I is correct.

Bioreactors serve as large vessels designed for the large-scale cultivation of cells to produce specific gene products for commercial purposes. Small volume cultures cannot yield appreciable quantities of products. To produce in large quantities, the development of bioreactors, where large volumes (100-1000 litres) of culture can be processed, was required.

Thus, bioreactors can be thought of as vessels in which raw materials are biologically converted into specific products, individual enzymes, etc., using microbial plant, animal or human cells. A bioreactor provides the optimal conditions for achieving the desired product by providing optimum growth conditions (temperature, pH, substrate, salts, vitamins, oxygen).
