data in fed-batch and perfusion mode using LC-MS data and multivariate analysis High cell density perfusion process development for antibody producing 

The fed-batch method adds nutrients once they are depleted. The perfusion method circulates medium through a growing culture, allowing simultaneous removal of waste, supply of nutrients, and harvesting of product. Paul Jorjorian, Global Director, Technology Transfer, Patheon, offers biopharmaceutical companies his advice on fed-batch versus perfusion processing technol 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. In fed-batch the product yield was increased by 40% to a relative value of 1.4 accompanied by a significant loss of culture viability indicating the detrimental effect. However, under perfused conditions not only the volumetric productivity was increased as expected, but also the relative product concentration reached a valueof 6.0 at viabilities of more than 90%.

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 This article concerns the comparison between batch and fed-batch fermentation based on productivity and including the analysis of the implications on product manufacturing cost.The calculation method of productivity is based on the assumption that batch production rate data are applicable to fed-batch fermentation and that, within a certain range of concentrations, the percent rate of change Parrish Galliher, Chief Technology Officer, Upstream, GE Healthcare Life Sciences Xcellerex, talks with BioPharm International about the challenges in bioman 2020-03-23 · Although both fed-batch Process C and a perfusion production process achieve much higher volumetric productivities than a conventional fed-batch process, the strategy for intensified fed-batch Process C using N-1 perfusion with only a 6-day duration is simpler and more robust in operation than a perfusion production using a larger amount of media and a perfusion device at N production stage Therefore, when switching from a fed‐batch to a perfusion mode, a new medium need to be developed which supports high cell densities, high productivity, and favorable product quality. We have developed a method for deriving perfusion culture media based on existing fed‐batch media and feeds. Perfusion vs fed-batch.

Whilst all major CDMOs in the market offer perfusion to some extent, it does not fit their business models to the same degree as batch manufacture.

perfusion culture processes. The USP stages of mammalian cell culture processes typically involve either fed‐batch or perfusion culture.

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".
