This experiment was conducted to investigate the feed value of Phellinus linteus meal. The chemical composition and particle size of Phellinus linteus meal was determined, and investigated the effect of partial substitution(0, 5, 10 and 20%) of dried Phellinus linteus meal on metabolizability and serum IgG concentration of layers. Crude fiber content of Phellinus linteus meal was higher, and crude protein and crude fat contents were similar level compare to corn, barley, and wheat. Dry matter metabolizability of Phellinus linteus meal was lower in 10 and 20% treatment than those of 0 and 5% treatment significantly(p<0.05). But, Phellinus linteus meal did not affect concentration of serum IgG.

The antioxidant and anticancer activities of Phellinus linteus, Inonotus obliquus, and Pleurotus ostreatus according to extraction methods were measured. The contents of polyphenolic compounds were higher in fermented extracts than those in water extracts. The contents were 192.4mg/100 $m{\ell}$ for Inonotus obliquus vinegar, 186.9 mg/100 $m{\ell}$ for Phellinus linteus vinegar, and 156.5 mg/100 $m{\ell}$ for Pleurotus ostreatus vinegar, respectively. EDA(electron donating ability) in Phellinus linteus that was highest among mushrooms was 83.9% in the water extract and 96.8% in the fermented extract. The growth of stomach cancer cells, SNU-719 was inhibited 62.4%, 65.5%, and 53.0% by Phellinus linteus vinegar, Inonotus obliquus vinegar, and Pleurotus ostreatus vinegar, respectively and also the growth of liver cancer cells, Hep3B was inhibited 67.1%, 68.3%, and 57.6% by Phellinus linteus vinegar, Inonotus obliquus vinegar, and Pleurotus ostreatus vinegar, while the growth of normal cell, DC2.4 was not affected. Even though Phellinus linteus and Inonotus obliquus showed higher inhibition in cancer cell growth, Pleurotus ostreatus can be efficiently used for antioxidant and anticancer activities due to their cheap price in the market.

Phellinus strains were collected from different areas in Korea. Of them, the fast mycelial growing strains were artificially cultivated on the oak logs to produce fruiting body. The varieties, Phellinus linteus ASI26099 (Korea Sanghwang) and P. baumii PBJS (Jangsoo Sanghwang) were grown under the same conditions as controls. Their cultivating characteristics including mycelial colonization, pinhead formation, and fruiting body formation rate were investigated on the logs. Basidiocarps of Phellinus strains HN00K9, HN6036, and ASI26099 were concentrically zonate and shallowly sulcate, and dark chestnut showing typical characteristics of Tropicoporus linteus (synonyum: P. linteus, Inonotus linteus, polyporus linteus), which is distinguishably different to PBJS. HN00K9 showed the highest yield of fruiting body among the mushroom strains. The β-glucan content in fruiting bodies of HN00K9 was 20% higher than those of other strains. Bioactive effects of polysaccharide samples from fruiting bodies of Phellinus strains, HN00K9, HN6036, ASI26099, and PBJS were assessed on cell viability and cytokine (IL-6 and TNF-α) inhibition and finally on anticancer to different human cancer cells.

Phellinus linteus (Hymenocaetaceae) has been used for the treatment of gastric cancer, noninsulin dependant diabetes, diarrhea, and menstrual irregularity. The antioxidative effect of cultivated fruit body of Phellinus linteus on low density lipoprotein oxidation was investigated. The MeOH and water extracts were examined by TEARS assay on human plasma LDL in vitro system. The MeOH ex. showed antioxidative activity, and then was fractionated into Precipitates, Water Insoluble fr., Water fro and ether fro The results showed that the lipophilic fractions, Water Insoluble fr. and Ether fr. of cu 1-tivated fruit body of Phellinus linteus, inhibited the oxidative modification of LDL.

The effects of dissolved oxy-gen(DO) concentration and DO control modes on cell growth in a 4L computer-controlled bioreactor system were investigated using Phellinus linteus WI-001, a producer of protein-polysaccharides having potent anticancer activi-ties. When DO was controlled at about 20%, maximum cell concentration and specific growth rate of the strain were observed to increase 36% and 64%, respectively, as compared to the experiment performed without DO control. By adopting cascade automatic control of DO ar 20% in a mixed automatic control mode using computer-con-trolled program, 19.5g/L of maximum cell concentration was obtained. These results showed that the mixed auto-matic control mode was the effective method for enhancing cell growth of the shear sensitive Phellinus linteus.

The context and upper surface of Phellinus basidiocarp become blackened, rimose and woody. The basidiocarp is sessile, dimidiate and elongate. The basidiospores are pigmented and ovoid to globose. Hymenial setae are $17{\sim}35{\times}6{\sim}8{\mu}m$. Nineteen isolates of Phellinus species, including Phellinus linteus, were used for sequencing of the internal transcribed spacer (ITS) region of the nuclear rDNA. Based on these sequence data, specific primers were designed for identification of Phellinus linteus isolates in Korea. The specific primers were within the ITS1 and ITS2 regions and were nested within the universal primers flanking the spacer regions. A total of four primers (the universal primers ITS-1F and ITS-4, and the specific primers PL-F and PL-R) were used for detection of Phellinus linteus collected in Korea. The length of the four amplification products of Phellinus linteus DNA were 800 bp (ITS-1F/ITS-4), two bands of about 720 bp (ITS-1F/PL-R and PL-F/ITS-4), and 610 bp (PL-F/PL-R). Among 23 isolates of Phellinus species collected in Korea, Thirteen isolates were identified as Phellinus linteus based on the presence of the four bands. The other species produced only the single ITS-1F/ITS-4 product.

This study was performed to determine the antimutagenic and cytotoxic effect of the Phellinus linteus methanol extract on Salmonella typhimurium TA98, TA100 and human cancer cell lines. In the Ames test, methanol extract of P. linteus alone did not exhibit any mutagenicity but showed substantial inhibitory effects against mutation induced by N-methyl-N'-nitro-N-nitrosoguanidine(MNNG), 4-nitroquinoline-nitroquinoline-1-oxide(4NQO), 3-amino-1,4-dimethyl-5H-pyrdo[4,3-blindol(Trp-P-1) and benzo(α)pyrene(B(α)P). The methanol extracts of P. linteus(200㎍/plate) showed approximately 78.3%, 78.7% and 88.1% inhibitory effect on the mutagenesis induced by 4NQO, Trp-P-1 and B(α)P. The anticancer effects of P. linteus extract against human breast adenocarcinoma(MCF7), human lung carcinoma (A549), human fibrosarcoma (HT1080), human hepatocelular carcinoma (Hep3B) and human epitheloid carcinoma (HeLa) were investigated. The treatment of 1mg/mL P. linteus extracts had the highest cytotoxicity against MCF7 (92.0%), followed by Hep3B (84.9%), A549 (84.2%) and HT1080 (82.9%). In contrast 1mg/mL treatment of P. linteus extracts had only 10∼40% cytotoxicity on normal human liver cell (WRL68).

To develop new functional materials, Saccharina japonica (S. japonica) was cultivated with Phellinus linteus (P. linteus) mycelia by solid culture. S. japonica was fermented with P. linteus mycelia. The various radical scavenging activities of extracts of fermented S. japonica with P. linteus mycelia (FSPM) were investigated and compared to the antioxidant capabilities of unfermented S. japonica and P. linteus mycelia. The antioxidant activities of FSPM extracts were evaluated using ferric reducing antioxidant power (FRAP) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity. FSPM showed stronger free radical scavenging abilities than P. linteus mycelia or S. japonica alone. These results indicate that fermentation of S. japonica changes its chemical nature and could provide beneficial antioxidant effects.

This study was carried out to elucidate phylogenetic relationship of a yellow lump, Phellinus linteus by comparing the nuclear ribosomal intergenic spacer (IGS) I region with that of other genera of basidiomycetes retrieved from Genbank. IGS I region of Phellinus linteus was 730 bp long and sequence homology was conserved in the 5' region, in particular $1{\sim}280\;bp$, and decreased in the direction toward the 3' end. ITS region was widely studied in phylogenies related to basidiomycetes, but IGS region was not well understood yet. Our study indicated that IGS region can be a good tool in phylogenetic study of basidiomycetes.

Artificial cultivation of Phellinus linteus was studied. The best yield (B.E. $9.4{\pm}1.6$) of basidiocarps including basidiospore was obtained using Quercus acutissima among the logs of Morus alba, Quercus acutissima, Alnus japonica, Castanea crenata. Optimum temperature and required periods for the basidiocarps formation were $25^{\circ}C$ and about 10 months, respectively.
