Details

Xylan is a polymer of glucose molecules and a major part of hemicellulose which hold the plant cell walls together. Aside from being the second most abundant polysaccharide, xylan is one of the foremost anti-nutritional factors commonly found in feedstuff raw materials. xylan is a gummy, mucous-like substance that is sometimes called wood gum. Materials used in animal feeds such as wheat and straw have plenty of xylan and are generally a large component of agricultural waste. For the feedstuff to be fully digestible and utilized properly, the plant cell wall must be broken down into smaller, usable fractions. Various xylanases are use in helping to degrade the cell walls on an industrial scale. Xylans are degraded by microorganisms and their xylanase enzymes. Recent studies on microbial xylanolytic activities have been geared towards induction of enzyme production under different conditions, purification, characterization and extensive use of this enzyme mainly for pulp bleaching purposes. Xylanase breaks down the hemicellulose component of plant cell walls. The action of xylanase enzyme helps break down the plant cell walls and it is this activity that has many applications in the food and paper-making industries, along with uses in agriculture and even for human health.  There are a number of different types of xylanases produced by different microorganisms. Each type of enzyme is most active under specific conditions, such as at different pH levels and temperatures. An example is the type of xlanase used for composting which become most active at high temperatures. In this condition the enzyme production and organic waste degradation activity will be at its optimal state.
Xylanase and other lignin-degrading enzymes are used to release sugars from cellulose, hemi-cellulose, starch and other carbohydrates in the compost pile. Enhanced growth of desired microbial cultures in the composting heap will prevent the increase of undesirable microbes and vertebrates that produce undesirable odor, bad appearance and potential pathogenic characteristics.  Over the years Shandong Sukahan  Bio-Technology Co., Inc. have done much research to find the different conditions in relation to the optimal activity of each type of xylanase and have helped biotechnology determine particular commercial and industrial application each type is best suited for.

• WHAT IS SUKAXY ALK?

  SUKAXY ALK is an alkaline xylanase preparation that degrades xylan. Xylan is a hemicellulose with a homopolymer backbone of xylose units that are linked by ß-1,4 glycosidic bonds. The xylan structure is linked with the lignin and pectin components which gives protection to the cellulose matrix. During cooking of pulps, the xylan is partially dissolved, modified and re-precipitates onto the fibre surface. The overall result of xylanase application is improved bleachability of the pulp with resulting reduction in usage of bleaching chemicals. The principal active ingredient of SUKAXY ALK is xylanase (endo-1,4-ß-xylanase, EC 3.2.1.8), an enzyme that degrades and solubilizes plant xylans. SUKAXY ALK is derived from the submerged fermentation of a high xylanase producing strain of bacteria for the paper and pulp industry and is particularly suited to the elevated temperatures and alkaline pH of kraft pulps in pul and paper industry. The major enzyme responsible for the hydrolysis of xylan are xylanase (endo 1,4-a-D-xylanohydrolase, EC 3.2.1.8) and a-xylosidase (1,4-ß-D-xylohydrolase, EC 3.2.1.37). Xylanase (1,4- D-xylan xylanhydrolase) catalyzes the random hydrolysis of 1,4- a-D-xylosidic linkages within the xylan structure thereby releasing xylo-oligosaccharides and xylobioses. ß-xylosidase hydrolyzes xylobiose and small xylooligo-saccharides to xylose.

• CHARACTERISTICS:

  SUKAXY ALK is available in liquid preparation as: SUKAXY ALK LQ 85 (with Activity of 85,000 U/mL) SUKAXY ALK LQ 17 (with Activity of 17,000 U/mL) SUKAXY ALK is most effective at: pH Range: 6.0 to 10.0 Temperature Range: 35°C to 65°C Unit Definition: The amount of enzyme needed to produce 1 µg xylose from xylan in one minute at specified conditions based on birchwood soluble xylan at pH 6 and 50°C over a 20 minute period.

• APPLICATION & DOSAGE:

  SUKAXY ALK xylanase can be added to pulp after cooking or oxygen delignification and prior to bleaching for the improvement of pulp bleachability. Almost every mill has unique conditions of fiber furnish, pulping technology and bleach sequence. The optimal dosage can also depend on the temperature, pH and consistency of the pulp. Call our technical personnel if you have questions regarding application and dosage of this product.
