- Аннотация: Adsorption of several crude and purified cellulases (from Trichoderma reesei. Penicillium verruculosum and Chrysosporium lucknowense) on indigo particles and Avicel cellulose was studied. Much higher amounts of protein were bound to indigo than to cellulose under similar conditions. For different purified enzymes, the quantity of bound protein per mg of adsorbent (indigo or cellulose) varied in the range of 57-111 and 0-62 mug mg(-1), respectively. However, in general, the enzyme adsorption on indigo was less specific than the adsorption on cellulose. Three endoglucanases, having the highest indigo-binding ability, demonstrated the best washing performance in the process of enzymatic denim treatment. These data confirmed our previous findings that certain cellulases, which have indigo-binding sites (clusters of closely located aromatic and other non-polar residues) on the surface of their molecules, may remove indigo from the denim fabric better than cellulases with lower content of hydrophobic residues exposed to solvent.
