摘要

The exopolysaccharide from Stereum hirsutum NX-22 (SHPS) was obtained by fermentation. The structure of SHPS was characterized by HPLC, infrared spectroscopy, ultraviolet spectroscopy. The main structure of SHPS was a kind of b-glycosidic bond polygalactose. Antioxidant activity tests showed that SHPS had certain scavenging effect on DPPH and hydroxyl free radicals. Maximum SHPS production of 5. 964 g/L was obtained at pH 7 and 25°C for 5 d in medium with 40 g/L corn flour, 3 g/L yeast powder, 0. 6 g/L MgSO₄, 1.0 g/L K₂HPO₄, and 1. 5 g/L KH₂PO₄. This study provides a useful reference for further development of medicinal value of S. hirsutum, especially for the preparation and application of its exopolysaccharides.
