Abstract:

Cultivation of wood-rotting mushroom, shntake (Lentinus edodes), on natural hardwood logs mainly outdoors has become well established in Japan especially (San Antonio 1981; Royse et al. 1985). Several patents have also been issued on the cultivation of shntake on artificial logs indoors (Fuzisawa et al., 1978, 1978; Mee, 1978). The main advantage of the artificial log cultivation is the short production cycle, which is about 6 months, compared to the natural log cultivation method that can take as long as 6 years. The artificial log cultivation method also makes it possible to cultivate shiitake throughout the year in northern hemisphere.

The spawn for shiitake cultivation on artificial logs is grown either on a solid medium such as sawdust or cereal grains, or in a liquid medium (Royse, 1985; Diehle and Royse, 1986; Pellinen et al., 1987). Although liquid mycelial spawn is not usually used for commercial mushroom production, it has some advantages over the solid mushroom spawn Liquid spawn is easily handled and large amounts can be produced rapidly and injected into the bed material effectively (Laniece, 1966).
