Sphingan, a class of biopolymers with high-molecular-weight exopolysaccharides synthesized as secondary metabolites by Sphingomonas species, has garnered considerable attention due to their versatile functional properties and wide-ranging applications. This review offers a comprehensive exploration of the structure-function relationships of three representative sphingans, including Gellan Gum, Welan Gum, and Sanxan Gum, with a focus on their unique rheological behavior, gelation mechanisms, and bioactive characteristics. The influence of environmental factors, such as temperature, pH, and ionic composition, on their physicochemical properties is systematically analyzed, providing insights into their adaptive functionalities. To address production scalability challenges, this review outlines critical strategies for enhancing sphingan biosynthesis, encompassing strain improvement through mutagenesis and genetic engineering, metabolic pathway optimization, and fermentation intensification. A promising avenue for sustainable production is the utilization of agricultural and industrial waste streams as alternative carbon sources, which not only reduces costs but also aligns with circular economy principles. Furthermore, the review examines the applications of sphingans in food, pharmaceuticals, agriculture, and the petroleum industry, highlighting their broad industrial relevance. Future research directions are proposed, focusing on structural modifications, functional enhancements, and innovative applications in emerging high-value sectors. This review provides a comprehensive understanding of sphingans, connecting fundamental insights with practical advancements, and offers a foundation for their broader commercialization and application.

鞘氨醇胶(sphingan)是一类生物高分子聚合物,主要由鞘氨醇单胞菌属(Sphingomonas)微生物在生长代谢中作为次级代谢产物合成。本文系统地梳理了结冷胶(Gellan Gum)、威兰胶(Welan Gum)、三赞胶(Sanxan Gum)等典型鞘氨醇胶的结构特征与功能关联,探讨了其流变性能、凝胶性能及生理活性的分子基础,并分析了温度、pH、离子类型等环境因素对其性能的调控作用。针对鞘氨醇胶生产成本高、产量低等瓶颈问题,总结了当前提高产量的关键策略,包括诱变育种、基因工程改造、代谢调控及发酵生产优化,并重点介绍了工农业废弃物作为替代碳源的可行性,展示了其低成本工业化生产的应用价值。此外,本文综述了鞘氨醇胶在食品、医药、农业、石油工业等领域的应用现状,并对未来研究方向进行展望,为推动其在高附加值领域的创新性转化提供思路。

Sphingan, a class of biopolymers with high-molecular-weight exopolysaccharides synthesized as secondary metabolites by Sphingomonas species, has garnered considerable attention due to their versatile functional properties and wide-ranging applications. This review offers a comprehensive exploration of the structure-function relationships of three representative sphingans, including Gellan Gum, Welan Gum, and Sanxan Gum, with a focus on their unique rheological behavior, gelation mechanisms, and bioactive characteristics. The influence of environmental factors, such as temperature, pH, and ionic composition, on their physicochemical properties is systematically analyzed, providing insights into their adaptive functionalities. To address production scalability challenges, this review outlines critical strategies for enhancing sphingan biosynthesis, encompassing strain improvement through mutagenesis and genetic engineering, metabolic pathway optimization, and fermentation intensification. A promising avenue for sustainable production is the utilization of agricultural and industrial waste streams as alternative carbon sources, which not only reduces costs but also aligns with circular economy principles. Furthermore, the review examines the applications of sphingans in food, pharmaceuticals, agriculture, and the petroleum industry, highlighting their broad industrial relevance. Future research directions are proposed, focusing on structural modifications, functional enhancements, and innovative applications in emerging high-value sectors. This review provides a comprehensive understanding of sphingans, connecting fundamental insights with practical advancements, and offers a foundation for their broader commercialization and application.
