Xylanase Enzyme
Xylanase is a carbohydrase that hydrolyses the beta-1,4 bonds in xylan, the principal hemicellulose in plant cell walls. It is produced by submerged fermentation, most commonly of Trichoderma or Aspergillus species, and supplied as a standardised powder or liquid declared in activity units rather than by weight, since enzyme strength and not mass determines the dose.

Application / Intended Use
Xylanase hydrolyses arabinoxylan. Pulp mills use it as a bleach-boosting pretreatment, reducing chlorine dioxide demand; bakeries use it to improve dough handling and loaf volume; feed mills add it to wheat- and rye-based poultry rations to reduce digesta viscosity and improve feed conversion.
