Abstract: The aim of this study is to determine the effect growing media on antioxidant properties and antimicrobial activities Pleurotus ostreatus(Jacq. ex Fr.) P. Kumm. In study, substrates were prepared with five tree sawdust (80%) waste (20% Tea Waste or Wheat Bran) at different ratios (80% Sawdust + 20% TW, 80% GW). methanol extracts from 19 ostreatus against microorganisms tested by agar ...

The enzymatic mechanisms involved in the degradation of phenanthrene by the white rot fungus Pleurotus ostreatus were examined. Phase I metabolism (cytochrome P-450 monooxygenase and epoxide hydrolase) and phase II conjugation (glutathione S-transferase, aryl sulfotransferase, UDP-glucuronosyltransferase, and UDP-glucosyltransferase) enzyme activities were determined for mycelial extracts of P....

ABSTRACT- Almost all oyster mushroom producers in Iran produce this kind of mushroom without any kind of casing soil. Although different kinds of casing soils are available for Agaricus bisporus, limited information is available regarding Pleurotus ostreatus. Availability of peat in many regions around the world is a concern and some researchers' efforts have been devoted to a search for altern...

Pleurotus ostreatus (P. ostreatus) is considered a high-quality food, rich in proteins and bioactive compounds important for maintaining human health. Lately, commonly used substrate oyster mushroom cultivation—wheat straw, more often replaced by alternative cellulose substrates originated from the agricultural food industry. Utilization of wastes cultivation has its added value: sustainable wa...

Pleurotus ostreatus is one of the most cultivated mushrooms worldwide. It a lignocellulolytic fungus on different substrates, whose more common raw material straw. The present study investigated biological efficiency as affected by age straw and growing media preparation process in four production cycles. content organic carbon significantly decreased during preparation, while total nitrogen, m...

Extracts of two edible mushrooms, Pleurotus sajor-caju (commercial) and Schizophyllum commune (wild) were used to compare the antioxidant antimicrobial properties. Aqueous three types organic solvents, like 50% ethanol, methanol acetone extracts in trial. DPPH scavenging activity P. extract was determined range 53.13% 85.08%, whereas S. observed 54.11% 97.19% at a concentration 5 mg/ml. The hig...

BACKGROUND Glycoside hydrolases (GHs) and accessory proteins are key components for efficient and cost-effective enzymatic hydrolysis of polysaccharides in modern, biochemically based biorefineries. Currently, commercialized GHs and accessory proteins are produced by ascomycetes. However, the role of wood decay basidiomycetes proteins in biomass saccharification has not been extensively pursued...

White rot fungi (WRF) are known to have the ability to degrade organic pollutants with a structure similar to lignin. Because of this, the degradation of polychlorinated biphenyls (PCBs) congeners no. 28, 52, 101, 138, 153 and 180 by substrate before fruiting (substrate) and/or after fruiting (SMS) from cultivated mushrooms Pleurotus ostreatus, Lentinula edodes and Agaricus bisporus was examine...

Total polyphenols and flavonoids contents, as well as ferric reducing antioxidant power (FRAP), metal ions chelating activity, reducing power assay and scavenging activity of DPPH and ABTS radicals in aqueous and methanolic extracts obtained from mycelium, primordium, and fruiting body of Pleurotus ostreatus in both fresh as dry, were evaluated. The total polyphenol content of dried samples was...
