Upstream Bioprocessing vs. Downstream Bioprocessing: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on October 5, 2024
Upstream bioprocessing involves culturing cells to produce biological products, while downstream bioprocessing focuses on purifying and processing these products.
Key Differences
Upstream bioprocessing entails the steps involved in growing cells or microorganisms to produce a desired biological product. Downstream bioprocessing, conversely, involves processing and purifying the product obtained from these cultures.
In upstream bioprocessing, the focus is on optimizing conditions for cell growth and product expression. In downstream bioprocessing, the emphasis shifts to efficiently separating the desired product from impurities and cell debris.
Upstream processes include the development of cell lines, media preparation, and fermentation. Downstream processes involve filtration, chromatography, and product refinement.
Quality control in upstream bioprocessing ensures optimal cell growth and viability. In downstream bioprocessing, quality control is crucial for ensuring product purity and meeting regulatory standards.
Upstream bioprocessing is characterized by its biological and cultivation challenges. Downstream bioprocessing faces challenges in separation technology and product recovery.
