Title: Conversion of conifer wastes into edible and medicinal mushrooms.

Description: Mushroom-producing white-rot fungi can be used to convert woodwaste into gourmet and medicinal mushrooms. White-rot fungi do not always readily colonize on conifer wood because of its extractives content. This study evaluated the resinous extractive content of loblolly pine (Pinus taeda), ponderosa pine (Pinus ponderosa), and an unknown species of southern yellow pine before and after treatment with the extractive-degrading fungi Aureobasidium spp., Ceratocystis spp., and Ophiostoma spp. Fungal treatment removed 70 to 99.9 percent of extractives. Scanning electron microscopy showed heavy mycelial growth of the colorless isolate Ophiostoma piliferum, with good sporulation, on the surface of loblolly and southern yellow pine chips, in the resin canals, and in the parenchyma cells within 4 to 5 days. The treated wood chips were used to cultivate lignolytic mushroom-producing, white-rot basidiomycetes of various Pleurotus species and two other fungi, Grifola frondosa and Hericium erinaceus. The results show that lignolytic white-rot basidiomycetes can easily colonize and produce mushrooms on treated conifer wood chips.

Keywords: Mushrooms, wood wastes, conifer wastes.
