About this talk

Recently, there has been a renewed interest in the field of continuous processing. Some key factors driving this interest are – availability of better cell retention devices, improved cell lines and culture medium capable of supporting high cell densities. These factors have contributed mainly in reducing the batch duration for making the required quantity of product, thus reducing the medium requirement and chances of batch failures significantly. With the continuous processing being considered as ‘back-in-the-game’, the question remains: Can the current perfusion technology compete or replace the conventional and widely preferred fed-batch technology? Two cases are discussed to compare the performance features of fed-batch and perfusion processes. In both the cases, the product output from perfusion process is significantly higher (2 to 5 folds) than that from fed-batch, due to combination of factors like higher cell density, higher cell specific productivity, lower accumulation of toxic metabolites etc. These cases demonstrate the potential of perfusion process in significantly increasing the product output. However, there are certain challenges and points to be considered before a company decides to switch to a perfusion platform. Some of these are highlighted in the article.
