Novel Taylor-Couette Bioreactor for Mammalian Cell Cultivation

In the pharmaceutical industry mammalian cell lines §are the primary expression system in the production §of therapeutic recombinant proteins. Despite its §diverse drawbacks, the stirred tank reactor serves §here as major workhorse for most applications. To §overcome the limitations faced, improved bioreactors §are needed to provide a more favorable in vitro §environment to mimic in vivo conditions. In order to §establish a suitable culture system, the cell s §responsiveness to environmental stress is evaluated §to identify and anticipate the impact of this §process parameter during cell cultivation. Based on §these studies, a novel bioreactor featuring good §mass transfer characteristics at low shear values §both in maximal magnitude as well as distribution is §constructed. Its unique cultivation microenvironment §enhances cell growth and protein production and §makes it superior to conventional stirred tank §reactors. Especially nowadays in the environment of §a fast growing and competitive market, governmental §price control and rising quality requirements, the §proposed bioreactor provides a suitable tool for §biopharmaceutical research, development, and §production.
