| Abstract: | Rhizoma Gastrodiae was involved in this paper to study the extro-polysaccharide fermentation of Auricularia Auricula by submerged culture.The levels of carbon rescores,nitrogen rescores,salt and Rhizoma Gastrodiae was determined at first.And then the fermentation medium was optimized by orthogonal experiment design as well.The results show that the best medium composition was glucose 40g/L,yeast extract 13g/L,Rhizoma Gastrodiae 10g/L,KH2PO4 and MgSO4 5g/L and 2.5g/L respectively. |
