As such, the batch process (including fed-batch) represents a sub-class. Using this framework, the generalized perfused process including immobilized cell versions is shown to offer the means for process optimization that exceeds in performance that of the basic batch or fed-batch process.

The fed-batch method adds nutrients once they are depleted. The perfusion method circulates medium through a growing culture, allowing simultaneous

Fed batch vs perfusion

Hybrid (fed batch upstream, continuous downstream) Continuous (perfusion upstream, continuous downstream) For the basis for this analysis we looked at a monoclonal antibody process at three scales (100kg/year, 500 kg/year and 2000kg/year) to represent the range we typically see in manufacturing. Currently, the large‐scale production of mAbs is based on production systems that use recombinant mammalian cells. 10 Fed‐batch (FB) bioreactors have become the default platform technology for large‐scale production of mAb due to their ease of scalability (up to 20,000 L), robustness, and high volumetric productivity. 11 In contrast to a FB bioreactor, a perfusion bioreactor operates Fed-batch culturing involves adding nutrients at varying intervals in the hope of extending the culture and improving yield.

An efficient fed-batch process with significantly reduced seed train and production duration was successfully demonstrated using ATF perfusion technology. The improved process involved the preparation of High Density Cryo-Seed-Intermediates (HDCSI) and n-1 seed expansion using ATF, and high seeding-density fed-batch production bioreactor.

Combining the perfusion mode (cell accumulation) and the fed-batch mode (product accumulation) the product yield was significandy increased toa relative value of 10.0 at final viabilities of still 65%. To compare the productivities between fed-batch and perfusion mode, space-time yield or overall volumetric productivity (g/L/day) and space yield (g/L) were used in this study. As such, the batch process (including fed-batch) represents a sub-class. Using this framework, the generalized perfused process including immobilized cell versions is shown to offer the means for process optimization that exceeds in performance that of the basic batch or fed-batch process.

Cells ino-culated an intensified process with seeding concentrations between 1.2 and 30 MVCmL-1. Continuous and dyna-mic cell-specific feeding was employed to sup-port optimal cell growth and productivities.

Fed-batch culture is, in the broadest sense, defined as an operational technique in biotechnological processes where one or more nutrients are fed to the bioreactor during cultivation and in which the product remain in the bioreactor until the end of the run. An alternative description of the method is that of a culture in which "a base medium supports initial cell culture and a feed medium is added to prevent nutrient depletion". It is also a type of semi-batch culture. In some

In both cases product is harvested at the end, in one batch. In continuous cultures product is perfused constantly or at regular intervals, fresh media and feed are constantly added, and in many cases cells are bled off to maintain an optimized population of healthy A potential game changer—perfusion in biopharma production. Perfusion promises great cost savings, so it is not surprising that it has received so much attention. Perfusion processes can deliver more product for a given bioreactor volume as they can maintain higher viable cell densities than traditional fed-batch processes.
