What are Xylanases used for?
Xylanases are often used to improve cereal processing and end product quality. In wheat bread making the use of these enzymes may result in higher bread volumes and improved loaf texture, while in the case of wheat gluten-starch separation they are used to increase gluten and starch yield and purity.
What is xylanase in food?
Specifically, xylanase hydrolyzes a principal component of hemicellulose called xylan and arabinoxylan. Xylanase is used in the food industry for bread making, the production of corn starch, clarification of fruit juice and wine; animal feeds, and alcoholic fermentation.
What is the importance of amylase?
Amylase is responsible for the breaking of the bonds in starches, polysaccharides, and complex carbohydrates into easier to absorb simple sugars. Salivary amylase is the first step in the chemical digestion of food.
What are the commercial applications of xylanase?
Commercial applications for xylanase include the chlorine -free bleaching of wood pulp prior to the papermaking process, and the increased digestibility of silage (in this aspect, it is also used for fermentative composting ).
How many xylanases are in the xylanase family?
Only a few xylanases belong to other families as GH5,7,8,16,26,43,52 and 62 families   . Particularly, the GH11 family xylanases shows a β-jellyroll folding, an overall molecular mass of less than 30 kDa and a high specificity to xylan .
Can you make xylanase from fungi?
Industrial-scale xylanase production can be accomplished using SSF by fungi, mainly Aspergillus and Trichoderma. Fungi are potentially useful for xylanase production because they secrete enzymes into the medium, and their enzyme levels are, generally, much higher than those of yeasts and bacteria [59,60].
Do xylanases work in dairy cows?
Several studies have reported that the mixture of supplemental fibrolytic enzymes with high xylanase activity produced a positive response in dairy cows in confinement [64,65]. Other studies have evaluated the use of xylanases to improve nutrient digestibility in other ruminants and in pigs .
