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 () 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 (NIFoS 764, Sanjo 701ho, and Sanmaru 2ho) were used. The productivity
of 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 compared to healthy logs. In terms of antioxidant activity, grown on
sawdust from fumigated logs showed higher values than those from other logs.
