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… 
Fungal Xylanases: Sources, Types, and Biotechnological Applications
Improved technical advancement systems, development of recombinant fungal expression systems by genetic approach will help in hyper-expression of xylanases and xylanase families for their production management at the industrial level.
Isolation and screening of xylanase producing fungi from forest soils.
Xylanases have gained a unique importance in the biotechnology and industries due to their potential applications and are major industrial applications in textile industry and household laundry detergents.
A Review of Xylanase Production by the Fermentation of Xylan: Classification, Characterization and Applications
The primary chain of xylan is composed of β-xylopyranose residues, and its complete hydrolysis requires the action of several enzymes, including endo-1,4-β-D-xylanase (EC3.2.8), which is crucial for xylan depolymerization.
Screening of xylanase producing microorganisms.
A screening of the bacterial and fungal strains was performed in order to select the microorganisms that could produce higher amount of xylanases, which are significant for further studies regarding lignocellulosic biomass biodegradation by an enzymatic complex.
Fungal Biodiversity Producing Xylanase Enzymes Involved in Efficient Uses of Xylanolysis
This review emphasizes the structure, properties, hydrolysis, occurrence, isolation and the biotechnological applications of xylan.
Recent Advances and Industrial Applications of Microbial Xylanases: A Review
Thermostable xylanases are ideally suited for use in industrial applications because of numerous advantages over thermolabile xylanase such as ability to work in broad temperature range, better substrate utilization and ability to tolerate high temperature in processes as well as better shelf life.
Production and Optimization of Xylanase Enzyme from Bacillus subtilis using Agricultural Wastes by Solid State Fermentation
Background: Xylan, a major hemicellulosic polysaccharide found in the plant cell wall, represents up to 30-35% of the total dry weight of land plants. It is a heteropolysaccharide made up of a
Utilization of corncob xylan as a sole carbon source for the biosynthesis of endo-1,4-β xylanase from Aspergillus niger KIBGE-IB36
The use of low-cost substrate approach for high production of endo-1,4-β xylanase has been developed successfully that can be consumed in different industrial applications especially in paper and pulp industry.
Xylanases has a wide range of applications in pulp and paper, food, animal feed, textiles and pharmaceuticals, and they are important in pulp biobleaching as alternatives to the use of toxic chlorinated compounds.
A detailed overview of xylanases: an emerging biomolecule for current and future prospective

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.
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.
Production of fungal xylanases
Xylanases, xylanase families and extremophilic xylanases.
Xylanase production in Aspergillus nidulans: induction and carbon catabolite repression
Of the three endo-β-(1,4)-xylanases secreted by A. nidulans, that of 24 kDa was not under carbon catabolite repression, whereas the other two, of 22 and 34 kDa, were under glucose repression mediated by the creA gene product.
Purification and properties of an extracellular xylanase from the thermophilic fungus Humicola grisea var. thermoidea
The enzyme was highly specific for xylan and degraded this substrate to produce xylo-oligosaccharides, suggesting that it is a β-1,4-endoxylanase (EC
Cellulase-free xylanases from Bacillus and other microorganisms.
Several xylanase-producing cultures are isolated and characterised, one of which (an alkalophilic Bacillus SSP-34) produced more than 100 IU ml(-1) of xylan enzyme activity, which makes them less suitable for pulp and paper industries.
