국내에서 재배하여 생산되고 있는 상황버섯의 일종인 PMO-P4균주에 대한 ITS 영역의 염기서열 분석을 실시하였으며 목질 진흙버섯으로 잘 알려져 있는 P. linteus와 함께 RFLP분석을 통하여 상호 비교한 결과 PMO-P4균주는 P. baumii로 판명되었다. 이 결과를 토대로 이미 보고되어 있는 Phellinus속 균주들과의 종간 ITS 영역의 상동성을 비교한 결과 48.6%-72.2%였으며 본 연구에서 비교한 종들 가운데서는 P. linteus와 상동성이 가장 높았으며 P. gilvus와 상동성이 가장 낮았다.

식용버섯으로부터 항보체 활성물질을 탐색하여 새로운 소재화 연구의 일환으로 상황버섯(Phellinus linteus) 균사체로부터 항보체 활성 물질을 분리, 정제를 하였으며 화학적 특성을 검토하였다. 정제는 상황버섯의 열수추출한 후, 열수추출물(PL-0)를 한외여과하여 분자량별로 5개의 획분을 얻었다. 이 중, 300kDa 이상의 획분(PL-5)을 DEAE-Sepharose FF 이온교환 크로마토그래피, Sepharose CL-4B 겔여과 크로마토그래피를 실시하여 PL-5-IIIa 획분을 얻었다. PL-5-IIIa 획분을 HPLC를 행한 결과 단일 피크로 나타났으며 정제다당 PL-5-IIIa의 분자량은 800,000Da으로 측정되었다. 정제다당 PL-5IIIa는 64.2%의 당과 29.6%의 단백질로 구성되었으며 구성당은 galactose가 43.1%, mannose가 40.6%, fucose가 15.8%로 나타났다.

An extracellular pigment production of three Phellinus sp. (Phellinus 421, P. linteus and P. hartigil) through submerged cultivation was investigated. The maximum brown pigment from culture broth was obtained from the precipitate by addition of 10% 1M HCI solution. This precipitate showed absorption characteristics with ${\lambda}_{max}$ of 360nm. The maximum production of extracellular pigment obtained at optimum medium and culture condition was 3.54 ($A_{360}$). The precipitate was fractionated by Sephadex G-75 gel chromatography, and the isolated brown pigment contained a large amount of polyphenol and the small amounts of sugar and protein. The brown pigment fraction was stable in temperature range of $30{\sim}60^{\circ}C$, pH range of $4{\sim}6$, sugar addition ranges of $1{\sim}5%$ and salt addition concentration of 3 molarity. Antioxidative activity of the brown pigment by TBA method was better than that of vitamin E (${\alpha}$-tocopherol).

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.

사람의 피부는 자외선, 오염된 공기, 화학 제품 등 환경에 끊임없이 노출된다. 이들로 인한 자유라디칼과 활성 산소는 피부세포에 큰 손상을 끼치게 된다. 캄보디안 상황버섯 열수, 에탄올 추출물의 기능성 화장품 소재로 활용하기 위하여 지방 산패 억제능 측정과 주름개선 효과 측정을 하였다. 캄보디안 상황버섯 열수, 에탄올 추출물에 금속이온을 첨가하여 지방산패 억제능을 측정한 결과 캄보디안 상황버섯 열수 추출물 보다 에탄올 추출물이 $Fe^{2+}$와 $Cu^{2+}$chelating 능력이 우수하였다. 캄보디안 상황버섯 에탄올 추출물의 경우 0.1 mg/ml, 0.5 mg/ml, 1 mg/ml의 농도에서 대조군인 butylated hydroxytoluene (BHT)보다 높은 지방산패 억제를 나타내었다. 캄보디안 상황버섯 열수, 에탄올 추출물은 산화 촉매제인 $Fe^2$를 함유한 지방 산패 억제능이 $Cu^{2+}$를 이용한 지방산패 억제능 보다 우수하였다. 주름개선 효과 측정으로 elastase 저해활성을 측정한 결과 캄보디안 상황버섯 에탄올 추출물은 0.01 mg/ml의 농도에서 50.7%의 저해활성을 나타내어, 대조군인 urosolic acid보다 높은 elastase 저해활성을 타나내었다. 또한 에탄올 추출물의 경우 0.1 mg/ml의 농도에서 약 50%의 저해활성을 나타내어 캄보디안 상황버섯 열수 추출물 보다 에탄올 추출물이 collagenase에 대해 높은 저해활성을 나타내었다. 이상의 결과에서 캄보디안 상황버섯의 에탄올 추출물은 지방산패 억제능이 우수할 뿐만 아니라 주름 개선 효과가 있음을 확인할 수 있었고, 주름 개선 화장품 소재로서의 가능성을 확인할 수 있었다.

Two species of cultivated Phellinus sp. were identified as P. baumii by internal transcribed spacer (ITS) sequence analysis. The fruit bodies of the examined strains were similar to those of naturally occurring strains, having a bracket-like form, yellow-to-orange color, and poroid hymenial surfaces. The DNA sequences of ITS region of both strains showed a homology of 99% with ITS1 to ITS2 sequences of P. (Inonotus) baumii strain PB0806.

Phellinus linteus mycelia have many pharmacological effects, although their pharmacological efficacy principles have not been known yet. In the course of screening for biological activity of the extracts of Phellinus linteus mycelia, we found strong antioxidative activity in some fraction of water-insoluble. Therefore, we tried to isolate the active principle(s) from the extract. The isolation of the active compound was guided by superoxide anion radical scavenging activity. As a result, caffeic acid was isolated as an active compound. The IC$\_$50/ of the compound was 3.05 $\mu$g/ml (16.9$\mu$M).

The purpose of this study is to evaluate the sensory characteristics and the taste components of Korean soybean paste (doenjang) with mushrooms such as Lentinus edodes, Ganoderma lucidum and Phellinus Lentinus. edodes doenjang turned out to have a good taste, odor and color, but Ganoderma lucidum and Phellinus liteus doenjang were worse than control doenjang in the taste, odor and color as well as in sensory evaluation. The contents of amino type nitrogen were higher in Lentinus edodes and Phellinus liteus doenjang than in control doenjang. Of organic acids, succinic acid was the most abundant and Ganoderma lucidum doenjang had a little higher acetic, butyric and propionic acid. Fructose and glucose were detected as free sugar of mushroom doenjang, of which glucose was considerably contained in Ganoderma lucidum doenjang, Total contents of free amino acid were 2.247 ∼ 2.833mg/100g in doenjangs added mushrooms. Glutamic acid and alanine were dominant in mushroom doenjangs.

Fermentation parameters were estimated by use of a vent gas analyzer coupled to a computer data acquisition system in cultivation of Phellinus linteus WI-001, pro-ducer of polysaccharides known to have potent anticancer activities. Oxygen uptake rate(OUR), a critical indicator of the cells activities, was calculated by applying oxygen mass balance. In addition, by dividing the oxygen uptake rate hy the total oxygen consumed, on-line estimation of the cells specific growth rate was successfully done. It was also possible to estimate cell concentration directly bt use of oxygen-cell yield($Y_{x/o}$ ) which was obtained based on a correlation between cell growth and total oxygen consumed.

The extract contents of various Phellinus species (Hymenochaetaceae) including P. linteus, P. baumii, P. pini and P. igniarius of domestic and foreign products, were examined to standardize the quality of these products. The differences of various extract contents were identified and compared between different species of Phellinus products. The thin layer chromatographic patterns were also analyzed and six unidentified samples were thought to originate from P. baumii and P. igniarius. The chemical standardization for the quality control of various origins could be suggested by this study.
