Recently, the incidence of oak wilt disease has been increasing in Korea, resulting in an increasing number of dead trees. In this study, we performed sawdust bag cultivation of shiitake (Lentinula edodes) using oak wilt-diseased logs and measured the antioxidant activities of the resulting mushrooms. For sawdust media, 4 types of logs (healthy, infected, dead, and fumigated ones) were used. As inocula, three strains of L. edodes (NIFoS 764, Sanjo 701ho, and Sanmaru 2ho) were used. The productivity of L. edodes from dead logs was similar to that from healthy logs. Except for the Sanmaru 2ho strain, fumigated logs and infected logs yielded a lower productivity of L. edodes compared to healthy logs. In terms of antioxidant activity, L. edodes grown on sawdust from fumigated logs showed higher values than those from other logs.
