硒对松口蘑深层发酵的作用研究

以松口蘑为材料,在发酵培养基中添加不同浓度的硒,测定分析了松口蘑菌丝体的生物量、多糖含量、硒的积累量。结果表明:0～40μg/mL的硒浓度对松口蘑菌丝体的生物量和多糖含量的增加都有促进作用,且随着浓度的增高促进作用加强,40μg/mL以上的硒浓度有抑制作用,随着浓度的增高抑制作用增强;硒浓度在0～50μg/mL时,硒在菌丝体中的积累量随着硒浓度的增加而增加,当硒浓度超过50μg/mL时,硒在菌丝体中的积累量开始下降。

The Effect of Selenium on the Submerged Fermentation for Tricholoma matsutake

Tricholoma matsutake Singer was used as material and cultured in the fermnetion medium supplemented with different concentration of selenium,and then the biomass,the content of polysaccharid and the accumulated content of selenium in mycelium of Tricholoma matsutake Singer was measured.The results showed that selenium promoted the biomass and polysaccharid content with its concentration ranged from 0 to 40 μg/mL,meanwhille,the higher the concentration was,the better its effect was;however,when its concentration was above 40 μg/mL,the opposite was got.The content of selenium in the mycelium rose up when its concentration became from 0 to 50μg/mL,and the content of selenium in the mycelium descended if its concentration was higher than 50 μg/mL.
