        Suillus granulatus is an ectomycorrhizal fungus that is associated with pine roots. S. granulatus is edible mushroom and known as the weeping bolete. S. granulatus is similar to S. luteus, but S. granulatus has a ringless stalk. We investigated in the growth characteristics of the 4 strains of S. granulatus with growth medium, temperature, and cellulase enzyme activities. NIFoS 1211 and 2701 showed the highest growth on PDA and NIFoS 1997 produced abundant mycelia on MMN. NIFoS 2615 was grown well on SDA. In spite of same species, the optimal media were different according to habitat of fruit body. The optimal temperature for mycelial growth of all strains was 25oC and NIFoS 2615 was also grown well at 30oC. All of strains on MMN liquid medium were typically grown at pH ranges from 5.8 to 6.2. The dry weights of S. granulatus strains were measured according to different inorganic nitrogen sources. All strains showed the highest dry weight on MMN and showed little difference on none contained nitrogen source, ammonium and nitrate media. We measured cellulase activity on carboxymethylcellulose (CMC) agar plates, and determined clear zone according to pHs. The 4 strains of S. granulatus showed the positive reactions in cellulase activity. All strains formed the height clear zone at pH 6.

        For centuries, Lentinula edodes called “Pyogo” in Korea has been cultivated as a high-grade edible mushroom in Asia. This is known as medicinal mushroom for cold prevention in oriental medicine. In the world market, this mushroom of Lentinula edodes is introduced as representative edible and medicinal mushroom in Asia. As consumer interest increases, Asian Lentinula edodes market is also growing. There is a record that Korea has already been used as a gourmet food on the royal meal table for the king in the 15th century Joseon Dynasty. In Korea's famous oriental book, it is cooked with many traditional foods because of the pharmaceutical efficacy of this mushroom. For long time ago, difference in cultivation as well as in mushroom growth of Lentinula edodes has studied in Korea. Recent advances in cultivation of selected high quality mushroom studied from substrate optimization using log and sawdust of oak tree. Cultivation of Lentinula edodes strain research controlled the production of large quantity of various substrate conditions. This mushroom mycelia and fruit-body were cultivated in log of oak tree and sawdust substrate cultivation in types of bioreactors. According to compared cultivation method, it presented the optimistic condition for the amount production of various Lentinula edodes strain in Korea.
