General description
Studies show that the signal sequence found in the xylanase gene is critical for protein production in E. coli. Loss of this sequence resulted in a significant reduction in expression.
Xylanase catalyses the degradation of xylan into xylooligosaccharides and D-xylose. It also breaks down hemicellulose. Xylanase is used for the production of biofuels, such as ethanol and xylitol. It improves the quality of bread and juices. Xylanase is used in biobleaching process and decreases environmental pollution.
Purified endo-β−(1→4)-xylanase from Thermomyces lanuginosus produced by submerged fermentation of a genetically modified Aspergillus oryzae microorganism
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in cellulosic ethanol research. For more information see the article in biofiles and Enzymes for Alternative Energy Research
Application
Xylanase has been used:
- in the isolation of hemicellulose and production of oligosaccharides[1]
- in viscosimetric assay
- in the comparison of commercial enzymes for the aqueous enzymatic extraction of corn oil from corn germ
- in the hydrolytic degradation of xylan

Is this enzyme powder soluble in water ? seems like particle dispersing in buffer at Ph 4.8 ?
1 answer-
The active components of xylanase X2753 are readily soluble in water at concentrations that occur in normal usage. However, water solutions will be turbid because of the wheat flour used for standardization of the enzyme.
