树舌灵芝发酵特性的研究

Fermentation characteristics of Ganoderma applanatum

研究了树舌灵芝摇瓶发酵过程中生物量、pH值、电导率、胞外粗多糖、纤维素酶活力的变化趋势。结果表明,在树舌灵芝发酵过程中,生物量和pH值均在5d后趋于稳定,电导率先下降3d后逐步上升,胞外粗多糖、纤维素酶活力均在3d时达最大值,此后逐渐下降,5d后基本趋于稳定。

The change trends of biomass, pH value, electrical conductivity, extracelluar polysaccharide and cellulase activity were studied during shake flask cultivation of Ganoderma applanatum. The results showed that the biomass and pH value became stable after 5 d, the electrical conductivity declined first and then increased gradually after 3 d, and both of extracelluar polysaecharide and cellulase activity reached the maximum at 3 d, then declined gradually, and became stable after 5 d.
