BACKGROUND Mushrooms in the genus Agaricus have worldwide distribution and include the economically important species A. bisporus. Some Agaricus species are inedible, including A. placomyces and A. pseudopratensis, which are similar in appearance to certain edible species, yet are known to possess unpleasant odours and induce gastrointestinal problems if consumed. We have studied the chemical c...

A meiotic DNA polymerase [DNA nucleotidyltransferase (DNA-directed), EC 2.7.7.7], which likely has a role in meiotic DNA repair, was isolated from a mushroom, Agaricus bisporus. The purified fraction displays three bands in SDS/PAGE, at molecular masses of 72 kDa, 65 kDa and 36 kDa. Optimal activity is at pH 7.0-8.0 in the presence of 5 mM Mg2+ and 50 mM KCl and at 28-30 degrees C, which is the...

Melanogenesis is a biosynthetic pathway for the formation of the pigment melanin in human skin. A key enzyme, tyrosinase, catalyzes the first and only rate-limiting steps in melanogenesis. Since the discovery of its melanogenic properties, tyrosinase has been in prime focus and microbial sources of the enzyme are sought. Agaricus bisporus widely known as the common edible mushroom, it's taking ...

OBJECTIVE The objective of this study was to evaluate the effects of dietary supplementation with Agaricus sylvaticus medicinal fungus in fasting glycemia of post-surgery patients with colorectal cancer. SCOPE Proctology Ambulatory of Federal District Base Hospital-Brazil. SUBJECTS Fifty-six colorectal cancer patients in postsurgery phase, stadiums phase I, II and II, which followed specifi...

The commercial growing of white mushroom (Agaricus bisporus) is a frequent activity in certain Spain regions as La Rioja. We report two cases of white mushroom workers suffering from asthma caused by hypersensitivity to basidiocarp and spores of white mushroom.

The culmination of the first half-century of investigations into the genome of Agaricus bisporus was marked by the first whole-genome sequencing for a strain of this species. The genome of a second strain of A. bisporus was sequenced the following year. While a structural view of the genome is now effectively complete, functional interpretations of the many gene sequences, supported by accumula...

Mushrooms of the genus Agaricus are noted for their pharmacological and culinary properties. In this study, it was performed a critical literature review, focusing primarily on aspects of the chemical composition of these mushrooms whose pharmacological properties and nutritional composition characterize them as functional foods. It was also discussed articles conducted in vitro and in vivo pro...

A well resolved phylogeny of the Agaricaceae based on partial rpb2 sequences is presented from a wide geographic and systematic sampling of the family and compared to phylogenies based on nrLSU and tef1 sequences. A smaller dataset of the family focusing on the Agaricus clade of nrITS sequences and a combined dataset were used to determine the position of several white-spored taxa from northern...

The medicinal mushroom Agaricus blazei Murill from the Brazilian rain forest has been used in traditional medicine and as health food for the prevention of a range of diseases, including infection, allergy, and cancer. Other scientists and we have examined whether there is scientific evidence behind such postulations. Agaricus blazei M is rich in the immunomodulating polysaccharides, β-glucans,...
