摘　　要：与陆地生物质相比,海洋生物质因具有光合作用效率高、生长速度快、碳水化合物含量高、不含木质素等优点,受到了越来越多的关注,被称为第3代生物质资源。红藻是典型的大型海藻,其细胞壁富含多糖。本文首先介绍了红藻的分布与组成,之后围绕红藻多糖的生物转化,分别综述了其在酶解制备琼胶寡糖和3,6-内醚-L-半乳糖以及发酵生产乙醇和有机酸方面的研究进展,并对未来红藻生物质的利用方向进行了展望。Compared with terrestrial biomass,marine biomass,called the third generation of biomass resources,has attracted more and more attention due to its higher photosynthetic efficiency,faster growth speed,higher carbohydrate content and zero lignin content.Red algae are typical large seaweeds enriched with polysaccharides in the cell wall.In this paper,the geographical distribution and chemical composition of red algae are described with a special focus on recent progress in the biotransformation of red algal polysaccharides for the enzymatic preparation of agar oligosaccharide and 3,6-anhydro-L-galactose and the microbial production of ethanol and organic acids.Moreover,future directions for the utilization of red algal biomass are discussed.
