Intensified fed batch
WebNov 9, 2024 · Since intensified fed-batch could rival the cell-specific productivity of a conventional fed-batch, we developed novel hybrid strategies to either allow for acceptable seeding densities without compromising productivity, or alternatively, to push the productivity the furthest in order to reduce timelines. Introduction WebOverview of the differences between traditional fed-batch and intensified process applications. Learn how to operate bioreactors at benchtop and pilot scale, focusing on perfusion processes. Learning Goals: Perfusion systems and their potential applications, as well as general knowledge on available cell retention devices
