[Immobilized biocatalysts in biotechnological processes].

In recent years, biotechnology has been stuck with the problem of choosing the most technologically convenient way of utilization of biocatalysts using bacterial cells or structural formations. Immobilization of bio-objects on solid carriers uses the advantages of heterogenic catalysis over homogenous like simple separation of byocatalyst from end product on completion of biotechnological process, and highly effective transformation or synthesis of organic compounds through biomass concentration in fermenter. In addition, immobilized biocatalysts exhibit better stability in case of exposure to aggressive temperatures, active environmental reactions, and "attack" of foreign microflora. Immobilized biocatalyzers can operate repeatedly and owing to the unique specificity show promise for wide application in aerospace and environmental medicine.
