Extending the knowledge on secondary metabolites and the effect of solvent of extraction in mushrooms, We investigated five mushrooms species; two cultivated edible (Agaricus bisporus (brown) and Agaricus bisporus (white); and three wild medicinal edible mushrooms Trametes versicolor, Ganoderma applanatum and Fomes fomentarius for total phenolic, total flavonoid and condensed tannins content. T...

With the rising awareness of a healthy lifestyle, natural functional foods have gained much interest as promising alternatives to synthetic functional drugs. Recently, wild Agaricus bisporus (Lange) Sing. Chaidam has been found and artificially cultivated for its thick fresh body and excellent taste, with its antioxidant and anti-hypoxic abilities unknown. In this work, the antioxidant potentia...

From a cDNA library, constructed from mushroom primordia, nine cDNAs were isolated which were either induced or specifically expressed during fruit body development and maturation of the basidiomycete Agaricus bisporus. These cDNAs varied in size from 372 to 1019 bp and hybridized to transcripts of 400-1600 nt. Four of the cDNAs were only expressed in the generative phase of the life cycle whil...

The biological activities of the lipodepsipeptides (LDP) white line-inducing principle (WLIP), produced by Pseudomonas reactans NCPPB1311, and tolaasin I, produced by R tolaasii NCPPB2192, were compared. Antimicrobial assays showed that both LDP inhibited the growth of fungi-including the cultivated mushrooms Agaricus bisporus, Lentinus edodes, and Pleurotus spp.--chromista, and gram-positive b...

During the past several years, reports have appeared concerning the separation and characterization of a variety of newly recognized nonprotein amino acids of plant origin (2-6). A number of these substances have been identified as derivatives of glutamine in which substitution by residues other than those represented by the common a-amino acids has occurred at the amide nitrogen atom (6-13). I...

Galbeta1-3GalNAc (T-disaccharide) and related molecules were assayed to describe the structural requirements of carbohydrates to bind Agaricus bisporus lectin (ABL). Results provide insight into the most relevant regions of T-disaccharide involved in the binding of ABL. It was found that monosaccharides bind ABL weakly indicating a more extended carbohydrate-binding site as compared to those in...
