As such, it plays a major role in micro-organisms thriving on plant sources for the degradation of plant matter into usable nutrients. 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. Xylans are the most abundant noncellulosic polysaccharides in hardwood and annual plants, where they account for 20%–35% of the total dry weight [103].

For instance, water absorption, stability, and workability can be improved with the use of this enzyme. Also, fermentation for alcohol production utilizes xylanase to release the gummy material, so it can be fermented. Xylanase, in synergism with several other enzymes such as mannanase, ligninase, xylosidase, glucanase, and glucosidase, can be used for the production of xylitol, from lignocellulosic biomass (Kuhad and Singh, 1993). Xylitol is a polyalcohol with a sweetening power comparable to that of sucrose (Parajó et al., 1998). Xylanase is any one of a class of enzymes produced by some microorganisms.

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. 2021-02-12 · Xylanase is a class of enzymes produced by microorganisms to break down a component of plant cell walls known as hemicellulose. Xylan is a polymer of glucose molecules and a major component of hemicellulose, helping to hold the cell walls together.
