Given below are two statements:
Statement I: In a bioreactor, small volume of cultures are developed in which useful bio-products are produced.
Statement II: In downstream processing, the products formulated with suitable preservatives are ready for marketing without testing of their quality.
In the light of the above statements, choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Both Statement I and Statement II are false
Statement I: In a bioreactor, small volume of cultures are developed in which useful bio-products are produced. — False. Small volume cultures cannot give enough product. Bioreactors were developed so that large volumes (100–1000 litres) of culture could be processed. A bioreactor gives the best conditions of temperature, pH, oxygen and nutrients for making the product.
Statement II: In downstream processing, the products formulated with suitable preservatives are ready for marketing without testing of their quality. — False. The formulated product is not ready without testing. It has to pass clinical trials and quality control testing first.
NCERT Extract:
Downstream Processing – “After completion of the biosynthetic stage, the product has to be subjected through a series of processes before it is ready for marketing as a finished product. The processes include separation and purification, which are collectively referred to as downstream processing. The product has to be formulated with suitable preservatives. Such formulation has to undergo thorough clinical trials as in case of drugs. Strict quality control testing for each product is also required. The downstream processing and quality control testing vary from product to product.”
