Fermentation is a metabolic process that converts sugars into acids, gases, or alcohol. This process occurs in yeasts and bacteria, as well as in muscle cells when faced with a lack of oxygen. In this paper, isolation, culture, purification and extracellular polysaccharides of strain Fomes fomentarius were studied. Extraction of polysaccharides from a culture based on F. fomentarius extracellular polysaccharides, extracellular polysaccharides fermentation experiments was optimized and compared, the optimal fermentation method was obtained; extracellular polysaccharides were sulfated, phosphorylated experiments, selenium acidified, discussed the preparation of derivative polysaccharides and microscopic detection, and finally studied extracellular polysaccharides on DPPH, The scavenging ability, superoxide anion radical and hydroxyl radical scavenging ability of the derived polysaccharides were compared. The results showed that the extracellular polysaccharide and derivatized polysaccharide of F. fomentarius had certain antioxidant activity.
