Pleurotus eryngii(King oyster) is one of the most promising mushrooms being produced on the domestic farms. The quality as well as quantity of Eryngii is sensitively affected by micro climate factors. To safely produce high-quality Eryngii all the year round, it is required that the environmental factors be carefully controlled by well designed structures equipped with various facilities and control systems. This study was carried out at the commercial mushroom cultivation houses to find out reasonable range of each environmental factor and yield together with economic and safe structures influencing on the optimal productivity of Eryngii. This experiment was conducted from Nov. 10, 2004 to Aug. 27, 2005 in Eryngii. cultivation houses. The environmental factors measured for this study were inside/outside temperature, relative humidity and $CO_2$ concentration in Pleurotus eryngii medium. In addition, the yield and quality of mushroom were made investigation. But the optimal productivity will be evaluated by considering the quality and quantity of mushroom production, energy requirements, facility construction and management cost, etc.

버섯재배에 피해를 주는 긴수염버섯파리의 발생양상을 알아보기 위하여, 경남 산청과 사천의 느타리버섯 재배사에서 성충과 유충 및 용의 밀도변동을 조사하였다. 긴수염버섯파리는 버섯재배 전기간 동안 유아등 및 배지에서 발견되었으며 버섯재배가 진행됨에 따라 밀도가 증가하였다. 유충의 경우 종균접종후 30일 경부터 배지에서 발생하기 시작하였다. 발생이 가장 많은 시기는 봄재배기간인 $3{\sim}6$월 하순이었고 $8{\sim}9$월 중에는 발생이 적었다. 가을재배시에 다시 밀도가 높아지며 겨울재배시에도 상당한 발생과 피해를 나타냈다. 가해양상으로는 유충이 배지와 균사를 가로지르며 섭식하고, 균사간 결합을 끊어서 균사생장과 발이가 불량하게 되고, 버섯대의 기부에서 주름살까지 파고들어 버섯형성과 상품성에 피해를 줄뿐만 아니라 배지도 직접 가해하였다.

The wild edible mushroom, Lentinus lepideus has recently been cultivated for commercial use in Korea. While the mushroom has been widely used for nutritional and medicinal purposes, the possible anti-hyperlipidemic action is unclear. The effects of dietary L. lepideus on plasma and feces biochemical and on the liver histological status were investigated in hypercholesterolemic rats. Six-wk-old female Sprague-Dawley albino rats were divided into three groups of 10 rats each. Biochemical and histological examinations were performed. A diet containing 5% L. lepideus fruiting bodies reduced plasma total cholesterol, triglyceride, low-density lipoprotein, total lipid, phospholipids, and the ratio of low-density to high-density lipoprotein. Body weight was reduced. The diet did not adversely affect plasma biochemical and enzyme profiles. L. lepideus reduced significantly plasma ${\beta}$- and pre-${\beta}$-lipoprotein, while ${\alpha}$-lipoprotein content was increased. A histological study of hepatic cells by conventional hematoxylin-eosin and oil red O staining revealed normal findings for mushroom-fed hypercholesterolemic rats. The present study suggests that a diet supplemented with L. lepideus can provide health benefits by acting on the atherogenic lipid profile in hypercholesterolemic rats.

This study was conducted to identify a suitable color of light for development of the fruit body in Hypsizygus marmoreus. To accomplish this, samples were irradiated with blue (475 nm), green (525 nm), yellow (590 nm), or red (660 nm) light emitting diodes (LEDs) to induce the formation of fruiting bodies after mycelia growth. The diameter and thickness of the pileus and length of stipes in samples subjected to blue LED treatment were similar to those of subjected to fluorescent light (control), and the lengths of the stipes were highest in response to treatment with the red LED and darkness. The commercial yields of plants subjected to blue and green LED treatment were similar to those of the control. In conclusion, cultivation of H. marmoreus coupled with exposure to blue LED is useful for inducing high quality fruit bodies as well as higher levels of ergosterol, DPPH radical scavenging activity, total polyphenol content and reducing power.

버섯 세균갈성색무늬병원균인 Pseudomonas tolaasii에 대한 독소저해균으로 보고된 Pseudomonas sp. HC1 균주의 배양적 특성과 최적 배양을 위한 대량배지를 선발하였다. CH1균주의 생육온도는 $20{\sim}40^{\circ}C$, pH는 5.0~11.0까지 넓은 범위에서 왕성한 생육을 보였다. 대량배양을 위한 효율적인 영양원 선발을 위하여 기본배지에 탄소원 fructose 등 18종, 무기질소원 $NH_4Cl$ 등 6종, 유기질소원 peptone 등 6종 그리고 아미노산 asparagine 등 11종을 각각 1%씩 첨가하였고, 무기염류 13종을 1 mM 농도로 첨가하여 각각에 대한 생육에 미치는 영향을 조사하였다. 또한 선발된 각각의 영양성분들에 대한 최적 농도를 조사하기 위하여 각각의 성분을 0.1%에서 4.0%까지 배지에 첨가하여 배양후 생육정도를 조사하였다. 그 결과, 대량배양을 위한 생육최적조건은 온도 $20^{\circ}C$, pH5, 탄소원 0.9% dextrine, 유기질소원 1.5% yeast extract, 무기질소원 0.5% $(NH_4)_2HPO_4$, 아미노산 3.0% cysteine, 무기염류 4 mM $FeCl_3$에서 왕성한 생육을 보였다.

본 연구에서는 한국에서 개발한 23개의 양송이 품종과 42개의 도입품종의 유전적 다양성과 집단 구조를 SSR 마커를 이용하여 분석하였다. 양송이 품종의 N_A는 약 13, H_O는 약 0.59, HE는 약 0.74, PIC값은 약 0.71 이었다. 양송이 품종은 군집분석에 의하여 3개의 Group으로 구분되었고 다양한 국가의 품종으로 구성된 Group2의 다양성이 높았으며, 구조분석에 의하여 2개의 subpopulation으로 구분되었고, 품종의 수가 많은 Pop2의 다양성이 높았다. 한국의 양송이 품종들은 주로 Group 3에 분포하고, subpopulation 간 분포에는 큰 차이를 보이지 않았다. 본 연구의 결과는 양송이의 육종소재의 개발, 다양성 확보 등과 같은 품종의 개발과정에 이용될 수 있을 것이다.

Purpose: The purpose of this study was to investigate the quality characteristics and antioxidant activity on consequent storage based on the temperature of new cultivar dew-drop pine mushroom (Lentinula edodes GNA01). Methods: Dewdrop Pine Mushroom were prepared under different storeage temperature (4, 10, $20^{\circ}C$). Results: Weight loss and hardness showed the least reduction rate when it was stored at $4^{\circ}C$ (p<0.05). The color value changed to dark brown at all storage temperatures during the storage period. When it was stored at $4^{\circ}C$, it maintained its initial color for a longer period than at different storage temperatures. With respect to the change in its viable cell count, the cells proliferated to less than 3.0 log CFU/g up to Ed: Please review the change. The earlier part was difficult to understand 2.83 log CFU/g until 15 days of storage at $4^{\circ}C$. On measuring the antioxidant activity of this mushroom, the polyphenol content was maintained without a large change until 9 days of storage at $4^{\circ}C$. The electron-donating action maintained high antioxidant activity, accounting for 81.99% until 12 days of storage from 83.08% during the initial storage at $4^{\circ}C$. When it was stored at $4^{\circ}C$, the sensory characteristics received the highest score among all items, such as appeaance, color, flavor and general preference, etc. Concolusion: In summary, new Cultivar Dewdrop Pine Mushroom (Lentinula edodes GNA01) can maintain its commercial value until the 12th day of $4^{\circ}C$ storage.

The retrotransposon marY1 is a gypsy family retroelement, which is detected ubiquitously within the fungal taxonomic groups in which mushrooms are included. To utilize marY1 as a molecular marker for the DNA fingerprinting of mushrooms, oligonucleotides marY1-LTR-L and marY1-LTR-R were designed on the basis of highly conserved regions from the multiple sequence alignment of 30 marY1 sequences retrieved from a nucleotide sequence database. In accordance with $\underline{Re}trotransposon$ $\underline{M}icrosatellite$ $\underline{A}mplified$ $\underline{P}olymorphism$ (REMAP) fingerprinting methodology, the two oligonucleotides were utilized together with the short sequence repeat primers UBC807 and UBC818 for polymerase chain reaction using templates from different mushroom genomic DNAs. Among the tested oligonucleotides, the marY1-LTR-L and UBC807 primer set yielded the greatest amount of abundance and variation in terms of DNA band numbers and patterns. This method was successfully applied to 10 mushroom species, and the primer set successfully discriminated between different commercial mushroom cultivars of the same strains of 14 Pleurotus ostreatus and 16 P. eryngii. REMAP reproducibility was superior to other popular DNA fingerprinting methodologies including the random amplified polymorphic DNA method.
