The exopolysaccharide (EPS) production by psychrophilic Antarctic yeast Sporobolomyces salmonicolor AL₁ reached the maximum yield in medium containing sucrose (50 g/L) and diammonium sulfate (2.5 g/L) after a 5-d fermentation (5.64 g/L) at 22 °C, the dynamic viscosity of the culture broth reaching (after 5 d) 15.4 mPa s. EPS showed a mannan-like structure and high molar mass, and did not affect cellular viability and proliferation of murine macrophages. It exhibited also a protective effect against the toxic activity of Avarol.
嗜冷南极酵母 Sporobolomyces salmonicolor AL₁ 的胞外多糖 (EPS) 生产在 22°C 下发酵 5 天后（5.64 g/L），在含有蔗糖（50 g/L）和硫酸二铵（2.5 g/L）的培养基中达到最大产量（5.64 g/L），培养液的动态黏度达到（5 天后）15.4 mPa·s。EPS 呈现甘露聚糖样结构和高摩尔质量，且不影响细胞活力和小鼠巨噬细胞的增殖。它还表现出对 Avarol 毒性活性的保护作用。
