본 시험은 상황버섯박의 사료가치를 조사하기 위하여 화학적 성분을 분석하고, 산란계를 이용하여 급여수준(급여사료의 0, 5, 10 및 20%)에 따른 대사율과 혈청 IgG 농도를 조사하였다. 영양적 조성에 있어서는 섬유질성 단미사료 수준 이상의 영양소를 함유하고 있으며, 산란계에 대한 대사율은 대조구에 비하여 상황버섯박 10 및 20% 첨가구가 유의하게 낮은 결과를 보였다(p<0.05). 그리고 혈청 IgG 농도에 있어서는 첨가수준에 따른 유의적인 차이를 발견할 수 없었다. 위 결과로 볼 때 상황버섯박은 섬유질 함량이 높아 단위 동물의 사료로는 제한적 사용이 불가피하며, 버섯의 약리성분은 추출잔류물이라는 특성으로 볼 때 그 작용을 기대하기는 어려울 것으로 판단된다. 또한 상황버섯박은 섬유질 함량이 높은 것으로 보아 단위 동물보다는 반추동물의 사료로 이용하는 것이 유리할 것으로 생각된다.

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.

rDNA내의 ITS region의 염기서열 분석 결과를 토대로 19종의 Phellinus 속균중 Phellinus linteus를 특이적으로 동정할 수 있는 primer를 제작하였다. 이 특이 primer는 ITS1과 ITS2내에 위치하며 이들 spacer region에 인접해 있는 universal Primer내에 위치해 있다. 총 4개의 Primer(universal primer인 ITS-1F와 ITS-4 그리고 특이 primer인 PL-F와 PL-R)가 한국에서 채집된 Phellinus 속균중 Phellinus linteus를 동정하는데 사용되었다. Phellinus linteus의 증폭된 DNA크기는 800bp(ITS-1F/ITS-4)와 720 bp(ITS-1F/PL-R과 PL-F/ITS-4)에 해당하는 2개의 band, 그리고 610 bp(PL-F/PL-R)인 것으로 나타났다. 한국에서 채집된 23종의 Phellinus속균중 13종이 Phellinus linteus인 것으로 확인되었다.

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.

본 연구는 Phellinus linteus와 관련 담자균류 속간의 IGS I 영역의 분석에 기초한 분류체계를 정립하기 위해서 실시하였다. 실험에 사용된 Phellinus linteus 균주의 IGS I 영역은 730 bp였고 다른 담자균류의 IGS I 영역과 비교시 5' 말단부위의 $1{\sim}280\;base$까지는 각 균주들간의 보존성이 높게 나타났으며 3' 말단부위로 갈수록 보존성이 감소하다가 다시 증가하는 경향을 보였다. 담자균류의 IGS 영역에 대한 연구가 앞으로 진행된다면 ITS 영역의 비교와 더불어 새로운 계통분류지표로 이용될 수 있을 것이다.
