Abstract: The effects of sawdust from cinnamon processing residue on the growth of Ganoderma lucidum were studied. The results showed that the growth rate of Ganoderma lucidum could be promoted by adding sawdust from cinnamon residue sawdust in different growth stages. The growth rate of mycelia could reach to 8.2~8.4 mm/d and the storage time of strain could be extended to 9 months when adding 75~150 g/L of cinnamon processing residue sawdust to the gar medium. The growth rate of mycelia could reach 8.4 mm/d and 9.3 mm/d when adding 200~300 g/kg and 300~500 g /kg of cinnamon processing residue sawdust to the primary seed medium and culture medium respectively, obvious higher than that of the control. Adding 450~600 g/kg of cinnamon processing residues sawdust and 75~100 g/kg of clay soil to medium for fruiting of Ganoderma lucidum could increase the biological conversion rate to 66%~72%.
