Mounting evidence indicated the capability of various microorganisms in biosynthesis of exopolysaccharides (EPSs). A wide range of evidence extensively investigated the ability of bacterial species for EPS synthesis and their favorable effects, so little is known regarding yeast species. Many factors like composition of growth media and fermentation conditions are related to the structural and physical properties of EPSs. The EPS protects the producer yeast strain against extreme environment. Researchers proposed that yeast EPSs have priority over bacterial EPSs because of high yields of EPS biosynthesis and easy separation methods from growth media. Besides, they have drawn increasing attention due to their interesting biological activities, food, pharmaceutical, and cosmetics applications. Although a limited number of studies exist, this review aims to highlight the EPS structure and various applications of known yeast species in detail.

越来越多的证据表明各种微生物在胞外多糖 (EPS) 的生物合成中的能力。大量证据广泛研究了细菌物种对 EPS 合成的能力及其有利影响，因此对酵母物种知之甚少。许多因素，如生长培养基的组成和发酵条件，都与 EPS 的结构和物理特性有关。EPS 保护生产酵母菌株免受极端环境的影响。研究人员提出，酵母 EPS 优先于细菌 EPS，因为 EPS 生物合成的产量高且易于从生长培养基中分离。此外，由于其有趣的生物活性、食品、药物和化妆品应用，它们引起了越来越多的关注。尽管存在的研究数量有限，
