Concept
Upstream processing encompasses all the steps involved in the preparation and cultivation of cells or microorganisms before the main product, such as a protein or metabolite, is harvested. It is a critical phase in biomanufacturing that includes cell line development, media preparation, and fermentation or cell culture processes to optimize yield and quality.
Relevant Fields:
Concept
Cell culture is a laboratory technique where cells are grown under controlled conditions, typically outside of their natural environment, to study their behavior, function, and response to various stimuli. This method is essential for biological research, drug development, and the production of vaccines and therapeutic proteins.
Concept
Fermentation is a metabolic process that converts sugars to acids, gases, or alcohol in the absence of oxygen, primarily carried out by bacteria and yeast. It is crucial in food production, biofuel generation, and has applications in biotechnology for producing various chemicals and pharmaceuticals.
Concept
Concept
Bioreactor design is crucial for optimizing conditions for biological processes, ensuring efficient production of desired products such as pharmaceuticals, biofuels, and biochemicals. It involves considerations of factors like mixing, oxygen transfer, temperature control, and scalability to meet industrial demands while maintaining product quality and process safety.
Concept
Cell line development is the process of creating genetically stable and reproducible cell lines for use in research, drug development, and biomanufacturing. It involves selecting and optimizing cells to ensure high productivity, stability, and desired biological characteristics over extended periods of culture.
Concept
