1, Crude polysaccharide promotes the growth of Suillus luteus, ammonium sulfate protein has no influence.

2, The promoting effect to Suillus luteus of the ethanol supernatant dried at room temperature is better than which dried at room temperature.

3, Moreover, Suillus spp. did not form the mycorrhizal association under low water content. However inoculation showed positive growth effect on young seedlings.

4, The three fungi also differed in base exchange capacity, with Paxillus involutus having the highest base exchange capacity and Suillus bovinus the lowest.

5, In order to obtain the maximal mycelia biomass of Suillus bovinus, Response Surface Methodology (RSM) was involved in this paper to optimize the culture medium and fermentation conditions.

6, Through the initial separation of Pleurotus ostreatus juice, analysis the influence of Pleurotus ostreatus juice on the mycelia growth of Suillus luteus in various treatment conditions.
