The immobilization of whole microbial cells has become an important tool in the development of biocatalytic processes in the pharmaceutical and food industry. Not only dead, i.e. non growing cells, but recently with higher priority living and growing cells are the biological species, for which simple and efficient polymeric carriers had to be found. In comparison to other methods, like adsorption or encapsulation, entrapment into a polymer network is the most widely used technique. The network can be formed on the basis of a)ionic interactions (ionotropic gelation of polyelectrolytes), b) of polycondensation reactions (epoxides, polyurethanes, silicones) or c) of polymerization reactions (crosslinking polymerization of vinylic monomers, oligomers or polymers). The characteristic features and the efficiency‐controlling parameters of some immobilized cells systems are discussed as illustrative examples.
