Given below are two statements: Statement I: In a bioreactor, small volumes 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:
Both Statement I and Statement II are false
Both statements are false:
1. Statement I: In a bioreactor, large volumes of cultures are developed, not small volumes, to produce useful bio-products like enzymes, antibiotics, or hormones. Hence, this statement is incorrect.
2. Statement II: During downstream processing, products are tested for quality and purity before being formulated for marketing. Hence, this statement is also incorrect.
