Study On Recycling Key Technique Of Spent Mushroom Substrate Of Special Edible Fungi In Xinjiang

Pleurotus ferula is originated in Xinjiang. It is a parasitic or saprophytic rare edible fungus on the asafetida, which is a kind of medicinal plant and growing in the desert. The used substrate of mushroom after the mushroom gained is named of Spent Mushroom Substrate (SMS), which is comprised of much lignin, hemicelluloses and cellulose, and aminophenol, fat, abundant mycelium albumen, mineral matters and secondary metabolize productions of mycelium. Pleurotus ferula is a rare kind of mushroom. The reports of the recycling of ferulae mushroom's SMS and measuring of nutritional components are rarely.In this research, SMS was offered by Ion Beam Bio-engineering center of Xinjiang University. The nutrient components information was obtained by the standard measure and analysis. The methods are the national standards. The results showed that the contents of cellulose and coarse fat were reduced; the content of coarse albumen was not changed which was contrasted to the substrate; the contents of phosphorus and calcium were increased; vitamins were abundant; the type of amino acids were completely.The effect of aquatic extraction substance from SMS of Pleurotus ferulae on mycelium growth of four edible fungi was conducted. The conclusion of this experiment was residue of Pleurotus ferulae could be a part of substrate of Lentinula edodes and Flammulinavelutipes. When the part of aquatic extraction substance from SMS of Pleurotus ferulae was 30% and 50%, the mycelium growth of Lentinula edodes and Flammulinavelutipes were quickest. The cultivation cycles of Lentinula edodes and Flammulinavelutipes can be shortened.There was a measure on cellulose enzyme activity of SMS, by determining the activity of the CMC enzyme and FP enzyme of the SMS, the optimum reaction conditions were 50℃, pH 5.0 and 45℃, pH 5.0.
