Application of xylanase

Xylanase can be used in the brewing and feed industries. Xylanase can decompose raw material cell walls and β-glucan in the brewing or feed industry, reduce the viscosity of materials in brewing, promote the release of effective substances, and reduce non-starch polysaccharides in feed grains and promote the absorption of nutrients. Utilize, and thus more readily available, soluble lipid components. Xylanase refers to the degradation of xylan to low
A general term for a group of enzymes of glycans and xylose, mainly including exo-β-1,4-xylanase endo-β-1,4-xylanase and - xylanase which can feed the non- Starch polysaccharide (NSPS) is decomposed into oligo-xylose with a small degree of polymerization to improve feed performance, eliminate or reduce the anti-nutritional effect of non-starch polysaccharides in animal stomach due to high viscosity and it can destroy the structure of plant cell wall. Improve the activity of endogenous digestive enzymes and improve the utilization of feed nutrients. In addition, xylanase is widely used in paper food and textile industries. The xylanase has a pH range of 3.5 to 6.0, a suitable temperature range of 40 to 60 ° C, and is resistant to high temperature granulation for a few minutes.
It can be added during the protein rest period or post-fermentation of the saccharification process. Usually 25~75 g/ton wort or fermentation broth. The optimum amount should be determined experimentally.
Xylan is the main component of wood fiber and non-wood fiber. During the pulp cooking process, the xylan is partially dissolved, denatured and redeposited on the surface of the fiber. If xylanase is used in this process, some of the redeposited xylan can be removed. This increases the porosity of the pulp matrix, frees trapped soluble lignin, and allows the chemical bleach to penetrate into the pulp more efficiently. In general, it increases the bleaching rate of the pulp and thus reduces the amount of chemical bleach used. The xylanase operated by Weifang Yurui Trading Co., Ltd. is a specific enzyme that degrades xylan, which only degrades xylan and does not decompose cellulose. The xylanase is formed by the interaction of different microorganisms, and the best effect can be obtained by using it in a certain pH and temperature range. Developed using bacterial strains for the paper industry, AU-PE89 is particularly suitable for high temperature and alkaline pH environments in kraft pulp.
