Abstract
Residue of poaceous (gramineous) crops, such as rice straw, comprises a huge quantity of biomass in Japan. We investigated the mushroom cultivation properties of poaceous crop residues and evaluated the potential of these residues as mushroom cultivation media. A total of 81 species, 97 stocks of edible mushrooms and 5 species of crop residues were used in this investigation. Each fungus was inoculated to the solid medium made by each crop residue, and mycelial growth was measured. Mycelial growth of fungi was fastest on rye straw medium, and 14 of 97 stocks grew more than 5.0mm/d. Mycelial growth on six-row barley straw was also rapid. Fungi of the family Pleurotaceae, such as Pleurotus ostreatus, and Morchella esculenta grew quickly on most crop residues.
