The VacciXcell Hybrid Bioreactor is a unique bioreactor system that supports both adherent and suspension culture. It applies the stir principle for suspension culture and the tide motion principle for adherent culture.
The VacciXcell Hybrid Bioreactor can switch from suspension culture to adherent culture by simply changing the impeller to the matrix vessel. The matrix vessel contains the carriers, BioNoc™ II, to which the cells adhere to and grow; it is oscillated up and down by a motor to submerge the carriers in the nutrient medium. The matrix vessel cylindrical in shape and perforated halfway. The perforated half is used for medium submersion, while the non-perforated half is used during
seeding. The nutrient medium remains at the bottom of the reactor vessel and is kept homogeneous by a built-in magnetic stirrer. Aeration occurs through headspace overlay and through the dissolved oxygen in the nutrient medium.
The advantage of using the VacciXcell hybrid bioreactor is its multi-functionality. In a start-up or R&D environment, determining which type of culture would yield the desired product the most is essential. The VacciXcell hybrid bioreactor gives its users exactly that option by being able to try out four (4) different types of culture namely: adherent culture using macrocarrier, adherent culture using microcarrier in a stirred tank environment, suspension culture and fermentation. By being able to do the design of experiment (DOE) using these four types of culture in one system, data gathering and
analysis would be easier and more efficient, resulting in lower total cost and shorter process development period.
