Abstract
The experiment results showed that the optimum conditions of submerged fermentation are as follows: optimal seed age 48 h, inoculation size 15%, culture temperature 25 ℃ and fermentation time 96 h. The optimum conditions for extracting polysaccharides from Flammuling velutipes mycelia by water bath extraction method are as follows: material-liquid ratio 1:60, temperature 60 ℃ and time of 90 minutes.
