Tehreem Mujtaba, Hareem Mohsin

Abstract

Introduction:
Xylan is most abundantly present polysaccharide after cellulose grouped as hemicelluloses. It is composed of D-xylopyranose residues. These polymers of hemicelluloses are broken by the enzymes called as xylanases.

Aims/Objectives:
The enzyme is abundantly produced by fungi, protozoans, snails, insects, marine algae, yeast, bacteria and crustaceans. Apart from the source of origin, microorganisms are promising candidates as a source for xylanase production. The bacterial xylanases have cellulose activity and also thermostable. The industrial methods used in production of food products, healthcare products and fuels usually produce toxic substances which can harm the environment. As a replacement, xylanases can play a major role to eradicate this environmental pollution. So, the purpose of this study is to review the industrial and biotechnological applications of xylanases.
Conclusion:
Xylanases produced for various industries are valuable in bioethanol production, animal nutrition, and wood pulp bio-bleaching. For commercial production of xylanases, microorganisms are considered as one of the best sources because of their diversity in habitats and species.
