| Summary: | ABSTRACT Alginate lyases depolymerize alginate and generate alginate oligosaccharides (AOS) and eventually 4‐deoxy‐L‐erythro‐5‐hexoseulose uronate (DEH), a monosaccharide. Recently, alginate lyases have garnered significant attention due to the increasing demand for AOS, which exhibit bioactivities beneficial to human health, livestock productivity, and agricultural efficiency. Additionally, these enzymes play a crucial role in producing DEH, essential in alginate catabolism in bacteria. This review explains the industrial value of AOS and DEH, which contribute broadly to industries ranging from the food industry to biorefinery processes. This review also highlights recent advances in alginate lyase applications and engineering, including domain truncation, chimeric enzyme design, rational mutagenesis, and directed evolution. These approaches have enhanced enzyme performance for efficient AOS and DEH production. We also discuss current challenges and future directions toward industrial‐scale bioconversion of alginate‐rich biomass. |
