Endo-1, 4-β-xylanase (Endo-β-1,
4-xylan, xylanohydrolase; EC. 3.2.1.8, commonly called xylanase) is an
industrially important enzyme which degrades xylan randomly and produces
xylooligosaccharides, xylobiose and xylose. It is mainly present in microbes
and plants but not in animals. Xylanases from fungal and bacterial sources have
been extensively studied and produced commercially. Its potential use in paper
industries has been discussed which is directly related to reduction in
environmental pollution. It has role in bio-bleaching paper pulp and increasing
pulp brightness. Besides, it can be exploited for ethanol production and as an
additive in animal feedstock to improve its nutritional value. Endo-1,
4-β-xylanase can also be exploited in baking and fruit juice industries. Here,
we reviewed its distribution, structural aspects and industrial/
biotechnological applications. Besides, we also discussed studies related to
cloning of the gene encoding endo-1, 4-β-xylanase with the objectives of
overproducing the enzyme and altering its properties to suit commercial
applications.
