Question

Assertion (A): Sterile environment has to be maintained in bioprocess engineering.
Reason (R): The term ‘sterile’ in microbiology and bioprocess engineering refers to the inability to reproduce.

• A. Both A and R are false
• B. Both A and R are true but R is not the correct explanation of A
• C. A is true but R is false
• D. Both A and R are true and R is the correct explanation of A

Answer 1

The correct option is C A is true but R is false

Bioprocess engineering deals with the development and design of equipment and associated processes for manufacture of various biological products on a large scale.

It is essential to maintain sterile conditions in bioprocess engineering to enable growth of only the desired cells in large quantities for manufacture of various biological products.

Sterile conditions in microbiology and bioprocess engineering refers to microbe free conditions. Sterile conditions require the complete absence of microorganisms including bacteria, fungus, and their spores. It is essential in order to avoid the possibilities of microbial degradation or contamination and hence interference occurring as a result of their presence.

In reproductive physiology, the term ‘sterile’ is used to refer to an individual who is unable to reproduce.

Hence assertion is a correct statement but reason is an incorrect statement.
