Xylanase (EC 3.2.1.8) is any of a class of enzymes that degrade the linear polysaccharide xylan into xylose, thus breaking down hemicellulose, one of the major components of plant cell walls. As such, it plays a major role in micro-organisms thriving on plant sources for the degradation of plant matter into usable nutrients. Xylans are the most abundant noncellulosic polysaccharides in hardwood and annual plants, where they account for 20%–35% of the total dry weight [103]. The use of these enzymes has been proposed for bread-making, juice and wine industries, xylitol production, extracting coffee, plant oils, and starch. 2017-10-24 · Xylanase (pronounced zy-lan-ase) is an naturally-occurring enzyme commonly found in microbes and fungi that can play a vital role in human digestion. Scientifically speaking, it is an enzyme that breaks down a type of fiber known as hemicellulose by converting one of its components (beta 1,4 xylan) into a simple sugar called xylose.

forms and mechanism of action of xylanase makes it possible to use it for bio-bleaching of kraft pulp and for desizing and bio-scouring of fabrics. Results revealed that enzymatic treatment leads to the enhancement in Xylanase (Endo-1, 4-β-D-xylan, xylanohydrolase, EC 3.2.1.8) is an important xylan degrading enzyme involved in the random cleavage of xylan to produce xylose, xylobiose and xylo-oligosaccharides. Xylanase is the name given to a class of enzymes which degrade the linear polysaccharide beta-1,4-xylan into xylose, thus breaking down hemicellulose, one of the major components of plant cell walls. As such, it plays a major role in micro-organisms thriving on plant sources for the degradation of plant matter into usable nutrients.

The food enzyme is free from viable cells of the production organism and recombinant DNA. This xylanase is intended to be used in baking and cereal‐based processes. Based on the proposed maximum use levels, dietary exposure to the food enzyme–total organic solids (TOS) was estimated to be up to 0.027 mg TOS/kg body weight (bw) per day in European populations. Danisco® Xylanase targets arabinoxylans in dietary fiber to mitigate their negative effects and generate additional energy.
