Reutilization of cultural waste of Grifola frondosa as the substrate of bottle cultivation of Hericium erinaceum was investigated. Using the cultural waste with Japanese beech (Fagus crenata) or Japanese oak (Quercus serrata, Quercus mongolica var. grosseserrata) sawdust yielded increases in fruit bodies of H. erinaceum relative to increases in its substitutive ratio. The yields of fruit bodies on cultural waste medium of G. frondosa were significantly increased by 1.2- or 1.3-fold compared with that on either the beech or oak sawdust medium, respectively. The optimal ratio of nutrition for cultivation in the cultural waste medium was determined to be 40-50%. Compared with cultivation using fresh cultural waste medium, cultivation using medium containing cultural waste aged for 28-56 days at 15 or 25 ℃ or aged for 14-28 days at 35℃ yielded a 1.1- or 1.2-fold increase in fruit bodies, respectively. These results suggest that cultural waste of G. frondosa may be useful as a substrate for sawdust based cultivation of H. erinaceum.
