Supplementation of mushroom compost at spawning and at casing with various refined and crude seed oils resulted in 1 to 1.5 lb/ft increases in mushroom yield. Supplementation at casing with ground seeds or protein-oil combinations caused 2 to 2.5 lb/ft increases in mushroom yield. Further evidence is presented for a relationship between lipid metabolism and the initiation of fruiting in the cul...

Aspergillus niger is known for its efficient excretion machinery. However, problems have often arisen in obtaining high amounts of heterologous proteins in the culture medium. Here we present a quick method using sandwiched colonies to evaluate transgenic strains for secretion of heterologous proteins. Expressing the ABH1 hydrophobin of Agaricus bisporus in A. niger, we showed that low producti...

the effect of various pesticides (diflubenzuro, malathion, mancozeb and carbendazim), disinfectants (calcium hypochlorite and formaldehyde) and oil cakes (sunflower and soy-bean oil cakes) commonly used as supplements in mushroom cultivation on the growth of the nematophagous fungus, arthrobotrys oligospora, was studied under in vitro conditions. carbenazim caused 99% inhibition of radial mycel...

the edible mushrooms (basidomycetes) have high nutritional value, promote the immune system, and as a source of natural antimicrobial substances have been used to cure bacterial infections since ancient times.various kinds of proteins with several biological activities are produced by mushrooms. in this research, in order to evaluate antibacterial activity of edible mushrooms, we isolated prote...

BACKGROUND AND PURPOSE Although molds are regarded as the main fungal allergen sources, evidence indicates that spores of Basidiomycota including Agaricus bisporus (A. bisporus) can be also found at high concentrations in the environment and may cause as many respiratory allergies as molds. The aim of the present study was to evaluate specific immunoglobulin E (IgE) and immunoglobulin G (IgG) a...

abstract edible white button mushroom is a secondary decomposer and the activity of other micro-organisms is necessary to decompose the raw compounds for its growth. actinomycetes bacteria due to their ability to decompose the compound molecules such as cellulose, lingo-cellulose and lignin, play an important role in the composting process for the mushroom. bacterial biomass of actinomycetes co...

introduction natural and man made radioactive sources exist in our environment they can enter into our food chains. one of these is the soil-mushroom-human chain. high level doses of natural radiation can cause hazards to humans. materials and methods samples of agaricus bisporus cultivated edible mushroom in tehran province- iran were collected from 7 farms. specific activity of 226ra, 228ra, ...
