章節(jié)摘錄
Covalent bonding method provides more permanent linkage between the enzyme and the supportmaterial. Covalent bonds can be formed under mild conditions, and the active site of enzyme mustremain free from covalent attachments. There is still some possibility for loss of activity of the enzymeduring bond formation mainly because ofchemical reaction. (iv) Adsorption One of the simplest methods for enzyme immobilization is by adsorption. Enzymescan be adsorbed physically on a surface-active adsorbent by weak physical forces such as van der Waals'forces or dispersion forces. Commonly used adsorbents are: alumina, clay, silica, anion-exchange resins,these support materials may have to be chemically or physically pretreated. Ion exchange resinsDEAE-Sephadex and carboxymethylcellulose (CMC) can also be used as support media. One of thedrawbacks with the adsorption procedure is that since adsorption is a non-specific process, many othersubstances may also be attached to the carrier in addition to the immobilized enzyme. Anotherdisadvantage of this method is that the loading of enzyme on a unit amount of surface is always very low,and the bonding strength is very weak, Still this method is followed for the following distinctadvantages: (i) the immobilization procedure is easy and simple ?。╥i) the adsorption process is reversible (iii) enzymes are not deactivated by adsorption. 4.6.2 Properties oflmmobilized EnzymesEnzymes are usually immobilized in particle or pellet form; but enzymes may be attached to, orentrapped within carriers in the form ofmembranes, tubes or fibers, based on the requirements of a givenapplication. In view of this, an immobilized enzyme may have different properties as compared to thesame enzyme in a free soluti n form. The method ofimmobilization and nature ofinsoluble carrier mayhave influence on the enzyme properties. The specific activity may reduce in the immobilized enzyme,particularly if a chemical process is involved in the immobilization method. The enzyme stability mayvary on heating or storage. The pH optimum can change by as much as two pH units for the immobilizedenzyme, mainly because ofthe new microenvironment as compared to the pure enzyme. ……?
