XYLANASE ENZYME

Xylanase 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. Xylanase plays a major role in micro-organisms thriving on plant sources for the degradation of plant matter into usable nutrients. 

Xylanases are produced by microbes like actinomycetes, bacteria and fungi. The major fungal species producing xylanase are Aspergillus sp., Fusarium sp. and Penicillium sp. Fungal xylanases have higher activity than bacteria or yeast.

XYLANASE FOR FOOD INDUSTRY

Xylanase transforms water-insoluble hemicellulose into soluble form, which binds water in the dough, therefore decreasing dough firmness, increasing volume and creating finer and more uniform crumbs. It significantly improves manufacturing conditions.

Xylanases and enzymes that hydrolyze complex cell wall are used to improve dough handling properties, to enhance bread quality, extend shelf life by reducing the staling rate.

Xylanase along with protease, lipase and a-amylase are significantly effective for obtaining bread with higher specific volume in microwave oven, as compared to the bread with no enzyme added. The texture profile analysis was greatly modified by xylanases and the firmness of breadcrumb was reduced.

the proofing dough volume is increased significantly, the time of dough formation and dough stabilization is shortened.

XYLANASE FOR ANIMAL FEEDING

Xylanases are very useful in manufacturing of animal feed. Xylanases reduce the viscosity and enhance the absorption rate by degrading the starch polysaccharides in rich fiber and barley-based feeds. Pre-treatment of agricultural silage and grain feed employed with xylanases increases the nutritional value and improves the feed digestion in ruminants. Similarly, feed supplementation combined with xylanases for broiler diets, not only increases growth performance like weight gain but also helpful in the yield production of poultry products. 

XYLANASE FOR PAPER AND PULP INDUSTRY

Xylanases catalyze the hydrolysis of xylans and therefore can hydrolyze precipitated xylans. This results in a reduction of the xylan concentration on the secondary wall of the fiber surface during enzymatic treatment with xylanase, particularly in hardwood pulps. Reducing the xylan concentration increases the permeability of fiber surfaces, improving bleachability.

The pulp and paper industries are attempting to bring changes to the bleaching process to minimize the use of chlorine to satisfy regulatory and market demands. Xylanases offer a cost-effective way for mills to realize a variety of benefits in bleaching. One main benefit is reducing Adsorbable Organic Halides (AOX) discharge. This is achieved primarily by decreasing chlorine gas usage. xylanase treatment can substantially improve the final brightness of bleached pulps while simultaneously decreasing bleaching costs.
