The button mushroom Agaricus bisporus is represented mainly by two varieties, a secondarily homothallic variety with predominantly heterokaryotic spores per basidia and heterothallic four homokaryotic spored basidium. Both varieties also differ in their recombination landscape the former showing crossovers (CO) at chromosome ends whereas latter has more evenly distribution of CO over chromosome...

BACKGROUND The available literature does not provide data on the application of probiotic strains in mushroom processing. The aim of the study was to evaluate the potential to use the L. plantarum 299v strain with documented probiotic properties in the process of lactic fermentation of button mushroom fruiting bodies (Agaricus bisporus). METHODS Fresh button mushroom fruiting bodies and cultu...

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) ...

mushroom production units of kermanshah province were sampled during 2012-13, and 50 fungal isolates were obtained. verticillium fungicola with the most number of isolates, tricoderma harzianum and trichothecium sp. were the most frequent fungi associated with the cultivated mushroom, agaricus bisporus. seven isolates were obtained from the cap of a. bisporus with following characteristics: col...

In this paper we report an eco-friendly route for the synthesis of sliver nanoparticles using Agaricus bisporus (white button mushroom) extract. The synthesized silver nanoparticles were confirmed and characterized by UV-Visible spectrum of the aqueous solution containing silver ions showed a peak at 420 nm corresponding to the surface plasmon absorbance of silver nanoparticles. Transm...

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, ...

Estrogen is a major factor in the development of breast cancer. In situ estrogen production by aromatase/estrogen synthetase in breast cancer plays a dominant role in tumor proliferation. Because natural compounds such as flavones and isoflavones have been shown to be inhibitors of aromatase, it is thought that vegetables that contain these phytochemicals can inhibit aromatase activity and supp...

We describe a modified Agrobacterium-mediated method for the efficient transformation of Agaricus bisporus. Salient features of this procedure include cocultivation of Agrobacterium and fruiting body gill tissue and use of a vector with a homologous promoter. This method offers new prospects for the genetic manipulation of this commercially important mushroom species.
