Downstream processing

Definition

Downstream processing refers to the series of steps required to purify and isolate biological products after fermentation or cell culture processes. This stage is crucial as it ensures the final product is safe, effective, and suitable for commercial use. It includes various techniques such as filtration, centrifugation, chromatography, and drying, which help in removing impurities and concentrating the desired product.

5 Must Know Facts For Your Next Test

1. Downstream processing is essential for obtaining high-purity products like enzymes, hormones, and vaccines from fermentation processes.
2. Techniques used in downstream processing can significantly affect the yield and quality of the final product, making optimization critical.
3. Filtration methods help in separating cells from the culture broth, while centrifugation is often used to clarify the liquid before further processing.
4. Chromatography techniques are pivotal in isolating specific components based on their chemical properties, allowing for targeted purification.
5. Downstream processing can also involve formulation steps, where the purified product is prepared for storage and distribution.

Review Questions

• How does downstream processing impact the overall efficiency of bioproduct production?
  • Downstream processing significantly impacts the overall efficiency of bioproduct production by ensuring that the desired product is isolated and purified effectively. If downstream processes are not optimized, it can lead to reduced yields and lower product quality. The methods employed during this stage must balance cost-effectiveness with the need for high purity to meet regulatory standards, thus directly influencing the economic viability of biotechnological applications.
