Microbial polysaccharides are multifunctional and can be divided into intracellular polysaccharides, structural polysaccharides and extracellular polysaccharides or exopolysaccharides (EPS). Extracellular polymeric substances (EPS), produced by both prokaryotes (eubacteria and archaebacteria) and eukaryotes (phytoplankton, fungi, and algae), have been of topical research interest. Newer approaches are carried out today to replace the traditionally used plant gums by their bacterial counterparts. The bacterial exopolysaccharides represent a wide range of chemical structures, but have not yet acquired appreciable significance. Chemically, EPS are rich in high molecular weight polysaccharides (10 to 30 kDa) and have heteropolymeric composition. They have new-fangled applications due to the unique properties they possess. Owing to this, exopolysaccharides have found multifarious applications in the food, pharmaceutical and other industries. Hence, the present article converges on bacterial exopolysaccharides.
微生物多糖具有多种功能，可分为细胞内多糖、结构多糖和细胞外多糖或胞外多糖（EPS）。由原核生物（真细菌和古细菌）和真核生物（浮游植物、真菌和藻类）产生的细胞外聚合物（EPS）一直是热门的研究对象。如今人们采用了新的方法，用细菌来源的多糖替代传统使用的植物胶。细菌胞外多糖具有广泛的化学结构，但尚未获得显著的重要性。从化学角度来看，EPS富含高分子量多糖（10至30 kDa），且具有杂聚组成。由于它们具有独特的性质，因而有新奇的应用。因此，胞外多糖已在食品、制药和其他行业中得到了广泛应用。因此，本文聚焦于细菌胞外多糖。
