Fructification and yield of the edible mushrooms Pleurotus pulmonarius and Stropharia rugosoannulata are clearly enhanced when wheat straw is supplemented with 30% Lolium perenne grass chaff. The bioactive compound in the methanol extract of grass chaff was identified as beta-adenosine. In vitro biological activity tests showed that 0.012 mg of beta-adenosine per ml of medium stimulated earlier...

The boron contents of 68 edible common macrofungi of Hungary were analysed. The average boron content of the examples was 11.74 mg/kg dry mass, this is higher than the average value of green plants of Hungary (7.4 mg/kg dry mass). Although the highest boron contents were found in the examples from woods near Budapest, the differences between the various sites are not significant. It seems that ...

Breast cancer is the most commonly diagnosed cancer among women in Western countries. Currently, there is no effective therapy for malignant estrogen-independent breast cancer. We have screened 38 species of edible mushroom on human estrogen-receptor positive (MCF-7) and estrogenreceptor negative (MDA-MB-231, BT-20) breast cancer cells to select potential agents with broad-spectrum antitumor ac...

The edible mushroom Pleurotus ostreatus has been studied as a potential crop to reduce agricultural solid wastes and increase mushroom production. P. ostreatus cultivated on various agricultural wastes singly i.e. rice straw (RS), rice husk (RH) wheat straw (WH), barley straw (BS), and cotton wastes (CW). The biological efficiency (B.E) was 25.61, 9.51, 22.6, 21.628 and 25.78 % while rounding u...

Edible fungi, mushrooms, are a popular food in Japan and over 15 cultured mushroom species are available at the food markets. Recently, constituents or ingredients of edible mushrooms have drawn attention because possibilities have been seen for their medical usage. Mycoglycolipids (basidiolipids) of higher mushrooms have been characterized as glycosylinositolphosphoceramides, having a common c...

The fungus Agaricus bisporus is commercially grown for the production of edible mushrooms. This cultivation occurs on compost, but not all of this substrate is consumed by the fungus. To determine why certain fractions remain unused, carbohydrate degrading enzymes, water-extracted from mushroom-grown compost at different stages of mycelium growth and fruiting body formation, were analyzed for t...

The mushroom of the genus Pleurotus in western China, called Bailinggu, is a precious edible fungus with high economic value. However, its taxonomical position is unclear. Some researchers regard it as a variety of P. eryngii, namely P. eryngii var. tuoliensis, whereas others consider it to be a subspecies of P. eryngii, viz. P. eryngii subsp. tuoliensis. A total of 51 samples representing seve...

The various synthetic substituted hydrazines, which cause tumors in animals, are briefly enumerated. To date, 19 of them have proved to be tumorigenic in animals. A number of these chemicals are found today in the environment, in industry, in agriculture, and in medicine, and the human population is exposed to a certain degree to some of them. Hydrazine also occurs in nature in tobacco and toba...

Arctic tundra is rich mushroom country and a number of high latitude fungi species can potentially be used as food. Different regions often play host to many of the same or similar mushroom varieties. Yet, people’s attitudes toward the same mushrooms—and mushrooms in general—vary widely both in temporal and geographical senses. The given work presents a study in ethnomycology—a field of inquiry...

Eleven different wild-edible mushroom species growing in the Black Sea region of Turkey were analysed for their element content. Specimens of mushrooms were gathered in Trabzon, Giresun and Ordu and analyzed for 31 elements by ICP-OES, four of which (Be, Sb, Te and Ti) were not detected. Whereas some minerals including Ag, As, Cd, La, Mo, Pb, Se, Y and Zr were detected in just a few mushroom sp...
