Conditions affecting lingzhi or reishi medicinal mushroom ganoderma lucidum (Agaricomycetes) basidiome quality, morphogenesis, and biodegradation of wood by-products in Argentina
Solid-state fermentation (SSF) with the medicinal higher Basidiomycete Ganoderma lucidum was studied as a strategy to use pine (Pinus radiata D. Don) and poplar (Populus nigra L.) wood chips and sawdust. Fruiting bodies were produced and the value of the biotransformed substrate was assessed. The hi...
