Bioreactors for Large-Scale Production — NEET Biology
✅ Asked in NEET 2024Small 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 optimum conditions for achieving the desired product by providing optimum growth conditions (temperature, pH, substrate, salts, vitamins, oxygen).
Bioreactors are large vessels (100-1000 litres) that enable commercial-scale production of biological products using microbial, plant, or animal cells—unlike small laboratory cultures that cannot produce appreciable quantities. NTA tests this by asking students to distinguish between small-scale culture limitations and large-scale bioreactor capabilities, or by asking what volume is processed in industrial bioreactors. The trap: students confuse laboratory cultures with industrial bioreactors, or forget the specific volume range (100-1000 litres). Remember: bioreactors maintain optimal conditions (temperature, pH, oxygen, nutrients) and scale up production from mililitres to thousands of litres, making them essential for pharmaceutical, enzyme, and vaccine manufacturing.
