The chemotactic response of wild-type Pseudomonas putida and P. tolaasii, and a phenotypic variant of each species, to Agaricus bisporus mycelial exudate was examined. Both P. putida, the bacterium responsible for initiating basidiome development of A. bisporus, and P. tolaasii, the causal organism of bacterial blotch disease of the mushroom, displayed a positive chemotactic response to Casamin...
Angiotensin I-converting enzyme (ACE) inhibitors derived from foods are valuable auxiliaries to agents such as captopril. Eight highly functional ACE inhibitory peptides from the mushroom, Agaricus bisporus, were identified by LC-MS/MS. Among these peptides, the most potent ACE inhibitory activity was exhibited by AHEPVK, RIGLF and PSSNK with IC₅₀ values of 63, 116 and 129 μM, respectively. The...
To promote the selection of promising monokaryotic strains of button mushroom (Agaricus bisporus) during breeding, 61 progeny strains derived from basidiospores of two different lines of dikaryotic parental strains, ASI1038 and ASI1346, were analyzed by nucleotide sequencing of the intergenic spacer I (IGS I) region in their rDNA and by extracellular enzyme assays. Nineteen different sizes of I...
A direct staining procedure is described for fluorescence microscopy of fungal nuclei, chromosomes and mitochondria. The fluorochrome is a benzimidazol derivative (33258 Hoechst) known to bind selectively to deoxyribonucleic acid at neutral pH. The advantages of 33258 Hoechst relative to Feulgen compounds used previously to stain these structures include a greater intensity of fluorescence, th...
Agaricus bisporus fruit bodies affected by La France disease contain a specific set of nine dsRNA molecules. A method was developed to isolate intact virus particles containing these dsRNAs. Using precautions to limit proteolysis, virus particles 34 nm in diameter were banded in a Nycodenz gradient together with the nine disease-associated dsRNAs and three proteins of M(r) 120K, 115K and 90K. T...
به منظور شناسایی هیفومیست های قارچزی متعلق به جنس cladobotryum نمونه هایی از بازیدیوکارپ هایی متعلق به جنس های russula، lactarius، agaricus وarmillaria با آلودگی های قارچی جمع آوری شد. قطعاتی از بخش های آلوده کارپوفور شامل تیغه، کلاهک یا پایه کشت داده شد. شناسایی جدایه ها بر اساس مشخصات مورفولوژیکی و برخی خصوصیات دیگر انجام شده و چهار گونه c. dendroides، c. polypori، c. variumو c. verticill...
This work had the dual objective of selecting a substrate for rapid mycelial growth of Scytalidium thermophilum and then comparing the growth and production of a brown variety of Agaricus bisporus on substrate non-colonized and colonized with S. thermophilum. Mycelial growth of S. thermophilum at 45 degrees C was significantly greater on potato dextrose yeast extract agar (0.58 mm/h) as compare...
background: white button mushroom (agaricus bisporus) is one of the most sensitive agricultural crops after harvesting and its antioxidant properties tend to decrease during post-harvest storage with the passage of time. objectives: the possible role of exogenous application of malic acid as dipping treatment on bioactive components and antioxidant properties of sliced white button mushroom dur...
dry bubble disease is one of the most important serious diseases of the cultivated white button mushroom (agaricus bisporus (lange) imbach). it is a cosmopolitan disease having a worldwide distribution. ten isolates of lecanicillium fungicola var. fungicola (preuss) zare and gams were collected from mushroom farms. sensitivity of the isolates to benomyl, carbendazim, carbendazim+iprodione and p...
