目的：研究不同培養(yǎng)條件對紅緣擬層孔菌菌絲產量和多糖量的影響。方法：通過單因素試驗確定液體發(fā)酵培養(yǎng)的最佳溫度、起始pH值、搖瓶裝液量、接種量、搖床轉速和發(fā)酵天數。結果：最適菌絲體液體發(fā)酵的條件是培養(yǎng)溫度28 ℃，發(fā)酵液起始pH 6.5，250 mL搖瓶裝40 mL培養(yǎng)液，接種量30％，搖床轉速175 r / min，發(fā)酵9 d。結論：優(yōu)選的培養(yǎng)條件有利于提高紅緣擬層孔菌菌絲產量和多糖的量。

Objective: To investigate different culture conditions affecting on the mycelia yield and polysaccharide content of Fomitopsis pinicola. Methods: To select the optimum temperature, pH, medium volume, amount of inoculation, shaking speed and fermentation period. Results: The most optimal liquid fermentation conditions were: culture temperature 28℃, pH 6.5, 40 mL medium in 250 mL flask, inoculum size 30%, shaker rotation speed 175 r / min, fermentation period 9 d. Conclusion: Optimal culture conditions are conducive to raising the mycelia yield and polysaccharide content of Fomitopsis pinicola.
