A-60 : Mycological Characteristics and Artificial Cultivation and of a Novel Phellinus linteus KACC 93057 Pstrain

Sanghwangmushroom, Phellinus linteus (PL) is a mushroom species belonging to the Hymenochaetaceae, Basidiomycetes. PL has been studied extensively for its extraordinary capacity of suppressing cancer or enhancing body immunity. The mycelial materials of PL have mainly been used as research samples worldwide because fruiting bodies was difficult to be artificially cultivated. Alternatively, P. baumii (variety, “Jangsu”) have been cultivated in Korea. However, fruiting body morphology of P. baumii is clearly different to that of PL. We found Pellinuslinteus. KACC 93057Phaving features of fast mycelial growth ratefrom Phellinus isolates collected in Korea. The optimum temperature for the mycelial growth was at 25-30°C and growth was optimal at pH 5-7. The mycelial growth of P. linteus was faster than P. baumii, other P. linteus isolates and other Phellinus spp. The fruiting bodies were successfully produced by artificial cultivation on oak and mulberry logs in a year. The fruiting bodies showed typical morphologies of P. linteus. The pore shape in basidiocarpis circular with 5-7 per mm, hyphal system is dimity, and basidiospores are ellipsoid. Internal transcribed spacer (ITS)-rDNA sequence analysis showed a homology over 98% with those of reference isolates of P. linteus Furthermore, antioxidant and immune activation efficacy of the fruiting bodies were evaluated by comparing with those of Phellinus spp.
