Xylan is the principal type of hemicellulose. It is a linear polymer of β-D-xylopyranosyl units linked by (1–4) glycosidic bonds. In nature, the polysaccharide backbone may be added to 4-O-methyl-α-D-glucuronopyranosyl units, acetyl groups, α-L-arabinofuranosyl, etc., in variable proportions. An enzymatic complex is responsible for the hydrolysis of xylan, but the main enzymes involved are endo-1,4-β-xylanase and β-xylosidase. These enzymes are produced by fungi, bacteria, yeast, marine algae… Expand
Fungal Xylanases: Sources, Types, and Biotechnological Applications
Xylanase is a class of hydrolytic enzymes which cleaves the linear polysaccharide, the major constituent of hemicellulose beta-1,4-xylan into xylose. The structure of xylanase is complex, repeatedExpand

Recent developments have shown that metabolic pathways can be transferred from one organism to another and proteins can be modified to gain conformational stability, suggesting that naturally occurring systems can be custom engineered to the situation in the fermentation tank. Expand
Biotechnology of Microbial Xylanases: Enzymology, Molecular Biology, and Application
Xylanases are hydrolases depolymerizing the plant cell wall component xylan, the second most abundant polysaccharide, which makes them more suitable in the paper and pulp industry than lignin-degrading systems. Expand
Molecular and biotechnological aspects of xylanases.
Many lines of evidence suggest that xylanases operate via a double displacement mechanism in which the anomeric configuration is retained, although some of the enzymes catalyze single displacement reactions with inversion of configuration. Expand
Xylan-hydrolysing enzymes from thermophilic and mesophilic fungi
Screening of 40 mesophilic and 13 thermophilic fungi indicated that enzyme activities capable of degrading oat spelt xylan extensively were produced by only a few of the mesophobic species investigated, which could be explained, in part, by their lack of β-xylosidase. Expand
