Bioreactors

Several key factors are essential for successful fermentation of pichia pastoris. Here comes a brief and simple overview on what is needed for process optimization in terms of the capability of the hardware used.  

Monoclonal antibodies have been used for testing kits and medical therapies across a wide range of applications. The most recent is to provide a potential treatment for patients suffering from Covid-19 infection. The production of monoclonal antibodies is well understood, scalable and standardized to the extent that it makes a good generic example of a modern bioprocess. This aspect will be the focus of this short overview. 

The shake flask is one of the standard laboratory tools for culture of microorganisms and cells. The bioreactor, conversely, is seen as a specialized, solution for commercial applications and academic departments such as chemical engineering. While there is a generic case to be made for this view, the realities of modern research in the biosciences have expanded the need for more information and semi-production capability at small scales.

The fed-batch technique is an important biotechnological process strategy. Unlike the simpler Batch strategy, the substrate for microbial growth is not administered all at once but added over time. This allows control over the culture growth and product formation, whilst avoiding reactor limitations. Despite these advantages, a fed-batch will require optimization, which can present its own challenges.

CHO (Chinese Hamster Ovary) cells are the most commonly used resource for complex recombinant proteins for therapeutic use. Their importance for bioprocessing is already significant and growing.  

The impeller, also known as agitator, is a key component of the bioreactor. It performs the important tasks of mixing, aeration, heat and mass transfer within the vessel. Learn about the different characteristics of various types of impeller and the importance of their designs.
