Enzymes - Xylanase

Xylanase is the name given to a class of enzymes which degrade the linear polysaccharide beta-1,4-xylan into xylose, thus breaking down hemi cellulose, one of the major components of plant cell walls.

An overview presentation is made on the potential application and current global status on the use of xylanase enzymes in paper and pulp biotechnology. Emphasis is on the need to screen and identify suitable xylanolytic enzymes compatible with availability of indigenous raw materials for pulp manufacture; i.e. importance of cellulase-free alkali-stable xylanase enzymes, particularly for developing viable technologies to effect pulp bleaching. Substantial reduction in the use of toxic chlorine compounds in the paper industry, which are currently in use for achieving increased pulp brightness, can be envisaged.

Effectively reduce the anti nutritional factor xylan in animal feeds, decrease the viscosity of chyme. increase the rate of release of nutrients from plant cells , and more effectively utilize the nutrients in the feed. Improve the immune system, increase the number of beneficial microorganism in the digestive tract of the animao and thereby reduce the number of harmful bacteria and increase animal survival rate. Promote feed digestibility and absorption and thus reduce per unit cost of the feed. reduce environmental pollution by increaseing the absorption of nitrogen and phosphorus.
