Changes of micromolecule carbohydrates during fruiting body formation of Phlebopus portentosus
At present,there is limited research on the nutritional physiology of Phlebopus portentosus,and there are no reports on the changes of micromolecule carbohydrates in the fruiting body of P.portentosus at different growth stages.In this study,the content of micromolecule carbohydrates in fruiting bodies of P.portentosus was determined and analyzed at different stages of fruiting body growth.The results showed that the content of trehalose and mannitol was relatively high in the fruiting bodies of P.portentosus,and the range of change was great during the growth process.The trehalose content at harvest stage was 13.72 times that at initial stage.Trehalose and mannitol played an important role in the transportation of carbon source in P.portentosus.Adding trehalose and mannitol to the culture medium increased the yield of fruiting bodies,and the yield increased by 4.15％when solely adding trehalose.Further research on revealing the nutritional and physiological rules of P.portentosus and improving the formula of culture medium will be continued.
