Pleurotus citrinopileatus is a popular edible mushroom in Korea due to their bright color, unique flavor and texture. This study was initiated to evaluate the effects of feeding dietary P. citrinopileatus fruiting bodies on plasma and feces biochemical and on the liver histopathology in hypercholesterolemic rats. Six-week old female Sprague-Dawley albino rats were divided into three groups of 1...

Comparative linkage mapping can rapidly facilitate the transfer of genetic information from model species to orphan species. This macrosynteny analysis approach has been extensively used in plant species, but few example are available in fungi, and even fewer in mushroom crop species. Among the latter, the Agaricus genus comprises the most cultivable or potentially cultivable species. Agaricus ...

Flammulina velutipes (enoki, velvet shank, golden needle mushroom or winter mushroom), one of the main edible mushrooms on the market, has long been recognized for its nutritional value and delicious taste. In recent decades, research has expanded beyond detailing its nutritional composition and delved into the biological activities and potential health benefits of its constituents. Many bioact...

Orellanine (3,3',4,4'-tetrahydroxy-2,2'-bipyridine-1,1'-dioxide) is a tetrahydroxylated di-N-oxidized bipyridine compound. The toxin, present in certain species of Cortinarius mushrooms, is structurally similar to herbicides Paraquat and Diquat. Cortinarius orellanus and Cortinarius rubellus are the major orellanine-containing mushrooms. Cortinarius mushrooms are widely reported in Europe where...

Shiitake mushroom, the common Japanese name for Lentinus edodes (Fig. 1), derives from the mushroom associated with the shii tree (Castanopsis cuspidate Schottky) and take, the Japanese word for mushroom (Table 1). Because Japan is the world leader in production of this type of mushroom, the mushroom is now widely known by this name. These mushrooms are renowned in Far East countries (e.g., Jap...

Volvariella volvacea, commonly known as the straw or paddy mushroom, had the following growth characteristics: minimum temperature, 25 degrees C; optimal temperature, 37 degrees C; maximal temperature, 40 degrees C; pH optimum 6.0. Optimal pH for cellulase production was 5.5. The optimal initial pH for cellulase production and mycelial growth was found to be 6.0. The pH and temperature optima f...

Enzymatic properties of glutamate decarboxylase (GAD) [EC4.1.1.15] obtained from the fruiting body of Flammulina velutipes were evaluated via protein isolation, purification, and characterization. To investigate the anatomical localization of GAD, crushed fruiting bodies were centrifuged; the supernatant and precipitate were subsequently subjected to enzyme reaction. GAD activity of the precipi...

The most com monly cultivated basidiomycetes worldwide and in Serbia are button mushroom (Agaricus bisporus), oyster mushroom (Pleurotus sp.) and shiitake (Lentinus edodes). Production of their fruiting bodies is severely afflict ed by fungal, bacterial, and viral pathogens that are able to cause diseases which affect yield and quality. Major A. bisporus fungal pathogens include Mycogone pernic...

In this study, we developed an efficient electroporation-mediated transformation system featuring Flammulina velutipes. The flammutoxin (ftx) gene of F. velutipes was isolated by reverse transcription-PCR. pFTXHg plasmid was constructed using the partial ftx gene (410 bp) along with the hygromycin B phosphotransferase gene (hygB) downstream of the glyceraldehydes-3-phosphate dehydrogenase (gpd)...

Two novel butenolides, isoravenelone (1) and ravenelone (2), and a large amount of a known compound, vulpinic acid (3), were isolated from the methanolic extract of the Japanese fungus Pulveroboletus ravenelii (Boletales). These structures were elucidated by two dimensional (2D) NMR, MS, IR and UV spectra, and X-ray crystallographic analysis.
