Preheating Treatment of Softwood to Enable its Use as Substrate for an Integrated Production of Mushroom and Ethanol

Short Introductive summary

This study was to evaluate the approach of preheating treatment to enable use softwood (pine and spruce) for an integrated production of edible mushroom and cellulose ethanol. It proves that the preheating, prior to a mushroom cultivation, can reduce softwood impedances to white-rot fungi, which allows and improves mushroom growing in the softwood. During the cultivation of edible mushroom, the softwood is delignified by the fungus and thus its recalcitrance is reduced. Consequently, an increased enzymatic saccharification of spent mushroom substrates is observed. A potential production of bioethanol from softwood can be therefore achieved using biological processes only.
