External Mass Transferively thin layer of biomass will be formed just beneath the support surface. If for example oxygen is the limiting substrate, this active layer will be in the order of 100 µm thick, which is of the same order of magnitude as the thickness of the boundary layer.

Description of the Support MaterialIt is not possible to describe all possible support materials, because every day new materials are being developed. In this chapter only hydrogels are considered. These gels can be divided into two groups: natural and synthetic gels. In general the support material needs to restrict the free migration of cells.

Immobilization at Large Scale by DispersionProducing microcapsules at large scale implies first caring about the dispersion processes. The droplet solidification step (gelation, membrane formation ...) generally brings less problems (reader will refer to Chapter 3). In this chapter, four technologies of producing droplet at large scale will be proposed for cell encapsulation purposes:
