This study evaluated three white-rot basidiomycetes for their potential to improve the ruminal degradation of wheat straw. Pleurotus ostreatus (PO), Pleurotus ostreatus-mutant (PO-M) and Trametes gibbosa (TG) were incubated on wheat straw for 30 days at 28 degrees C. Neutral detergent fiber (NDF), acid detergent fiber (ADF), crude protein and in vitro dry matter digestibility (IVDMD) were deter...

Trichoderma asperellum is one of the species which can be isolated from contaminated Pleurotus ostreatus cultivation substrate with green mold disease. This study focused on the relationship between high temperature and infectivity of T. asperellum to P. ostreatus. Antagonism experiments between T. asperellum and P. ostreatus mycelia revealed that high temperature-treated P. ostreatus mycelia w...

The edible mushroom Pleurotus ostreatus has been studied as a potential crop to reduce agricultural solid wastes and increase mushroom production. P. ostreatus cultivated on various agricultural wastes singly i.e. rice straw (RS), rice husk (RH) wheat straw (WH), barley straw (BS), and cotton wastes (CW). The biological efficiency (B.E) was 25.61, 9.51, 22.6, 21.628 and 25.78 % while rounding u...

Mushrooms have been used as food supplement from times immemorial not only for their nutritive value, but also for their medicinal properties. This investigation attempts to update the present cultivation status and project the future prospects of the oyster mushroom, Pleurotus ostreaus for its biomedical potential. Comparative analysis of the yield and the chemical composition of clusters of P...

Decolourization of azo dyes by Pleurotus ostreatus, a white-rot fungus capable of lignin depolymerization and mineralization, is related to the ligninolytic activity of enzymes produced by this fungus. The capacity of P. ostreatus to decolourize the azo dye Orange II (OII) was dependent and positively co-linear to Mn(2+) concentration in the medium, and thus attributed to Mn(2+)-dependent perox...

In this study the biodegradative activity of Pleurotus ostreatus was tested against a natural waste (Coir) along with a synthetic polymer waste (Nylon 6). Lignin modifying enzymes such as laccase, lignin peroxidase and manganese peroxidase activity were tested for coir and nylon 6 degradation in solid substrate fermentation. Enumeration of degradation with loss of weight, lignin degradation ass...

The types of carbon source and nitrogen source used as well as the C:N ratio in the medium influenced lovastatin production by Pleurotus ostreatus. The maximum value of the lovastatin yield was obtained in a medium that contained organic nitrogen.

Pleurotus ostreatus as one of the most commercialized and popular fungi species was cultivated and consumed as traditional food for long time in many Asian countries like China, Korea and Japan [1], it contains many biological active materials, such as protein, fiber, carbohydrates, fat, trace elements and ash. Polysaccharide, one of the main bioactive components of P. ostreatus has received mo...

Laccase activity of Pleurotus ostreatus is significantly increased by the addition of apple pomace. Among various conditions, the best concentration of apple pomace and cultivation time for the production of laccase by P. ostreatus was 2.5% and 9 days, respectively. Reverse transcription polymerase chain reaction analyses of laccase isoenzyme genes, including pox1, pox3, pox4, poxc, poxa3, and ...
