摘要

Xylan is one of the most abundant polysaccharides in nature and presents a structural complexity characterized by a heterogeneous polymer composition. Comprising various sugar subunits and associated acids linked through a diverse array of bonds, xylan poses challenges for complete degradation. This review article provides a comprehensive overview of xylan's structure, the role of xylanolytic enzymes in its degradation, and the industrial applications of xylanases in sectors, such as paper and pulp, food, textiles, and pharmaceuticals. Furthermore, it also discusses the use of advanced biotechnology tools, such as nano-biotechnology and genetic engineering, particularly through CRISPR/CAS technology, for enhancing the thermostability of xylanases. This article also provides insights into emerging trends in xylanase research, including bioprospecting novel thermostable xylanases from metagenomes, protein engineering, synthetic biology, and the integration of biorefinery. Finally, it highlights the importance of regulatory frameworks and standardization initiatives for ensuring the quality and the sustainability of xylanase-based technologies. Overall, this review offers valuable insights into the multifaceted role of xylanases in biotechnology and industrial bioprocessing while outlining future directions for research and innovation in this field.
