Webthan it is with fed-batch processes (Figure 1). Perfusion does, however, allow for a combination of a smaller operational footprint and fewer production runs. For example, a continuous perfusion process could use 1.2 to 1.7 times more media annually than a comparable fed-batch process. On the other hand, a comparable fed-batch process may WebThis type of perfusion is similar to fed-batch with a comparable risk of product quality issues. Figure 2. Side-by-side application of enhancing a legacy simple fed batch (glucose) with a fed-batch process and concentrated perfusion-based fed-batch process. The concentrated fed batch was operated at 1.2 maximum VVD.

Perfusion-Based Approaches for Upstream Intensification

WebApr 7, 2024 · The most commonly used intensified processes are operated using a perfusion or fed-batch seed bioreactor enabling a higher than usual seeding density in the fed-batch production bioreactor. Hence, as part of the growth phase is shifted to the seed bioreactor, there is a lower split ratio, which increases the criticality of the seed bioreactor ... WebAbstract.
