MICROBIAL XYLANASES AND THEIR INDUSTRIAL APPLICATIONS AS WELL AS FUTURE PERSPECTIVES: A REVIEW

Nisha Sharma, Nivedita Sharma

Xylan is the most abundant and principal type of hemicellulose. It is a linear polymer of β-D xylopyranosyl units linked by (1–4) glycosidic bonds. Xylanases are most predominantly present in plant cell walls and are produced by different kinds of microorganisms like bacteria, fungi, protozoans and some yeast. Cellulase-free xylanases are important in pulp biobleaching as alternatives to the use of toxic chlorinated compounds because of the environmental hazards and diseases caused by the release of the adsorbable organic halogens. Xylanases has a wide range of applications in pulp and paper, food, animal feed, textiles and pharmaceuticals. In this review, we have focused on the studies of structural composition of xylan, sources of xylanases, production of xylanases and their potential industrial applications.
