Pleurotus ostreatus strains were cultured in liquid medium and on wheat straw. The yields of lovastatin were compared.

Background: Cigarette smoke can trigger oxidative stress. An alternative to overcome the harmful effects of cigarette is through antioxidants. White oyster mushrooms (Pleurotus Ostreatusostreatus or P. ostreatus) are a source exogenous antioxidants because many contain active compounds f...

The oyster mushroom (Pleurotus ostreatus) is one of the most important edible mushrooms worldwide. The mechanism of P. ostreatus fruiting body development has been of interest both for the basic understanding of the phenotypic change of the mycelium-fruiting body and to improve breeding of the mushrooms. Based on our previous publication of P. ostreatus expressed sequence tag database, 1,528 un...

In the brewing industry, spent brewery grains (SBGs) are byproducts with a low economic value. The potential use of this leftover as a substrate ingredient for Pleurotus ostreatus fruiting body cultivation and enzyme production was evaluated. The best substrate mixture for P. ostreatus mycelium growth comprised 30% wheat bran (WB), 68% beech sawdust (BS) and 2% CaCO3. On the substrates containi...

The olive oil extraction process yields liquid waste byproduct known as olive mill wastewater (OMW), which presents a major environmental problem, if not treated before dissipation. The large amounts of OMW generated, combined with its high polluting power as well as its high chemical oxygen demand (COD) concentrations, represent the main difficulties in finding a solution for the management of...

Bacteria were isolated from the mycelial surface of Pleurotus ostreatus and their role in fruiting body induction (fructification) of the edible mushroom P. ostreatus was investigated. Analysis of the bacterial community that colonized the mycelium showed that the species composition and numbers of culturable bacteria differed according to the developmental stage of P. ostreatus. In particular,...

BACKGROUND Total three Pleurotus species (P. ostreatus, P. sapidus, P. florida) was compared for ligninolytic enzyme production grown with Coralene Golden Yellow, Coralene Navy Blue and Coralene Dark Red azo dyes in liquid medium under shaking condition. RESULTS The biodegradation competency varied from species to species and it was found that P. ostreatus, P. sapidus and P. florida to 20 ppm...

The objective of this research was to evaluate the oyster mushroom Pleurotus ostreatus- (Jacq.: Fr.) Kumm. cultivation in substrates based on different combinations of wastes (leaf, pseudo-stem and pseudo-stem + leaf) and banana cultivars - Musa spp. (Thap Maeo, Prata AnãPelipita and Caipira) during 49 days. Organic matter loss in the substrate by action of the fungus was also evaluated during ...

The use of wooden crates for composting a mixture of 70% grass, (Digitaria decumbens), and 30% coffee pulp, combined with 2% Ca(OH)(2), was studied as a method for preparing substrate for the cultivation of Pleurotus ostreatus. Crate composting considerably modified the temperature pattern of the substrate in process, as compared to pile composting, where lower temperatures and less homogeneous...
