Although xylanase inhibition activity is detected in all parts of the wheat plant throughout development, XIP-I protein is located predominantly in the grain tissue, where it appears at a late stage in grain development and persists after germination (Elliott et al 2003). Xylanase is sometimes used in conjunction with other cell-wall degrading enzymes, such as pectinase and cellulase, to clarify the juice, so it becomes clear. Besides this, the chemical reactions often produce by-products toxic to fermentation; indeed, in the decomposition of lignocellulosic material, besides the liberation of sugars, products may be formed that are derived from the degradation of glucose (hydroxymethylfurfural), xylose (furfural), and lignin (aromatic and phenolic compounds and aldehydes). This process is experimental and the keywords may be updated as the learning algorithm improves. The amino acid sequence is similar to two Trichoderma xylanases (approximately 56% identical amino acids), and also shows at least 40% identities with the xylanases from Bacillus circulans, B. pumilus and B. subtilis [17].
