Descrizione

β-glucans, are consisting of linear β-D-glucosyl residues linked through β-1,3 and/or β-1,4 glycosidic bonds. The degradation of β-glucans in nature is catalyzed by β-glucanases. These enzymes constitute an important biotechnological aid in reducing the amount of chlorine required for bleaching in pulp and paper industry, the bioconversion of lignocellulosic materials into fermentative products, the improvement of digestibility of animal feedstock and the clarification of juices.
β-1,4-Xylans are consisting of a homopolymeric backbone of β-1,4-linked D-xylopyranose units and short side chains. β-1,4-Xylanases are the key enzymes that hydrolyze the backbone structure of β-1,4-xylans to initiate degradation of the complex polysaccharides by microorganisms.These enzymes have attached considerable research interest due to their worldwide commercial applications (textile, paper and pulp, foodstuff, animal feed, pharmaceutical and biofuel production), both alone and in combination with other enzymes.
