प्रश्न
How has the development of bioreactor helped in biotechnology?
Advertisements
उत्तर १
The importance of using a bioreactor is that in a bioreactor the raw materials are biologically converted into specific products. Bioreactors provide the optimal conditions to obtain the desired product by providing growth conditions such as temperature, pH, vitamins, and oxygen.
उत्तर २
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 the microbial plant, animal or human cells.
