Question:
The separation and purification of the biological product after completion of the biosynthetic stage in a bioprocess is known as
The separation and purification of the biological product after completion of the biosynthetic stage in a bioprocess is known as
Show Hint
Upstream = Production
Downstream = Separation & purification

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Bioprocessing involves two main stages:
• Upstream processing → Growth and production phase (biosynthesis)
• Downstream processing → Recovery, separation, and purification of product
Step 1: Understand the given condition.
The question refers to processes after biosynthesis is complete.
Step 2: Identify correct stage.
After production, the product must be:
• Separated from cells/media
• Purified for use This stage is called: \[ \text{Downstream processing} \]
Step 3: Analyze other options.
• Upstream → before production
• Quality control → testing stage
• Sample processing → not specific term here
Step 4: Final conclusion.
Thus, the correct answer is: \[ Downstream processing \]
• Upstream processing → Growth and production phase (biosynthesis)
• Downstream processing → Recovery, separation, and purification of product
