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
The key enzyme activity in this product is provided by xylanase, which hydrolyzes the (1,4)-β-D-xylosidic linkages in xylan.
Application:
Xylanase has been used:
in the isolation of hemicellulose and production of oligosaccharides
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
