After the formation of products in the bioreactors, it undergoes through a series of processes before it is ready for marketing as a finished product, is called ?

Options

A. Upstream processing
B. Dowsteram processing
C. Elution
D. Transformation

Answer

**Step-by-Step Solution:**

1. **Understanding the Context**: The question refers to the processes that occur after the formation of products in a bioreactor. This is a crucial phase in biotechnology where products are prepared for marketing.

2. **Identifying the Processes**: The processes that occur after product formation include separation and purification of the desired product from impurities and unwanted materials.

3. **Defining Downstream Processing**: The series of processes that the product undergoes after biosynthesis is known as downstream processing. This includes various steps such as separation, purification, and formulation of the product.

4. **Differentiating from Other Options**:
- **Upstream Processing**: This refers to the initial stages of product development, such as media preparation and inoculum development, and is not the correct answer.
- **Elution**: This is a specific technique used in downstream processing to separate materials but does not encompass all the processes involved.
- **Transformation**: This refers to the uptake of foreign DNA by bacteria and is unrelated to the product preparation process.

5. **Conclusion**: Based on the definitions and processes discussed, the correct term for the series of processes that occur after product formation in a bioreactor is **downstream processing**.

**Final Answer**: Downstream processing
