Immobilizowane alfa-amylazy i celulazy w zastosowaniach praktycznych

Today, more and more products made in biotechnological processes involving enzymes. The stability of the enzyme under process conditions are subjected to the immobilization on solid supports, which leads to a heterogeneous biocatalyst that can be used in several cycles or continuous processes. The article discusses the techniques presented in the literature immobilization of enzymes hydrolyzing starch and cellulose. Includes the method of immobilization in/on polymer and inorganic carriers and different ways of binding of the enzyme to a solid support. Particular attention is focused on mesoporous silica (mesoporous silica) (SBA-15) as a very attractive media for biocatalysts. Starch and cellulose are the main components of biomass, which is seen as an alternative raw material for ethanol production, i.e. second generation biofuels. Developing an effective biocatalyst for the conversion of biomass is the challenge of the XXI century.
