Dyes released into the environment have been posing a serious threat to natural ecosystems and aquatic life due to presence of heat, light, chemical and other exposures stable. In this study, the Pleurotus ostreatus (a macro-fungus) was used as a new biosorbent to study the biosorption of hazardous malachite green (MG) from aqueous solutions. The effective disposal of P. ostreatus is a meaningf...

A heteropolysaccharide (PS-I) and an insoluble glucan (PS-II) were isolated from the alkaline extract of edible mushroom Pleurotus sajor-caju, cultivar Black Japan. The polysaccharide was found to consist D-glucose D-galactose in a molar ratio 3:1. Based on total acid hydrolysis, methylation analysis, NMR experiments (1H, 13C, DQF-COSY, TOCSY, NOESY, ROESY, HMQC, HMBC), structure repeating unit...

This work was conducted to investigate dietary supplementation of oyster mushroom fruiting bodies on biochemical and histological changes in hyper and normocholesterolemic rats. Six-week old female Sprague-Dawley albino rats were divided into three groups of 10 rats each. Feeding a diet containing a 5% powder of Pleurotus ostreatus fruiting bodies to hypercholesterolemic rats reduced plasma tot...

Lippia alba is a plant that has antifungal activity against Aspergillus, Penicillium and Trichoderma genera as well as against human pathogenic microorganisms; however, there are no records on its effect on basidiomycetes which are responsible for white rot of wood. The objective of this study was to evaluate the antifungal activity of L. alba for the control of the white-rot fungus Pleurotus o...

Four laccase isozyme genes, Psc lac1, 2, 3 and 4 have been cloned from the edible mushroom, Pleurotus sajor-caju. The genes display a high degree of homology with other basidiomycete laccases (55-99%) at the amino acid level. Of the laccase genes isolated, Psc lac1 and 4 displayed the highest degree of similarity (85% at the amino acid level), while Psc lac3 showed the highest degree of diverge...

In this study, the effects of different cellulosic wastes on nutritional values Pleurotus ostreatus (Jacq.) P. Kumm. were investigated. Dry matter, moisture, protein, fat and ash contents analyzed according to AOAC methods. Crude protein determined by Kjeldahl method Soxhlet extraction, using ether as a solvent, respectively. Chemical composition such dry crude organic matter 93.5-93.7%, 6.3-6....

Catalases are ubiquitous hydrogen peroxide-detoxifying enzymes. They participate in fungal growth and development, such as mycelial growth and cellular differentiation, and in protecting fungi from oxidative damage under stressful conditions. To investigate the potential functions of catalases in Pleurotus ostreatus, we obtained two catalase genes from a draft genome sequence of P. ostreatus, a...

Pleurotus ostreatus is an industrially cultivated basidiomycete with nutritional and environmental applications. Its genome, which was sequenced by the Joint Genome Institute, has become a model for lignin degradation and for fungal genomics and transcriptomics studies. The complete P. ostreatus genome contains 35 Mbp organized in 11 chromosomes, and two different haploid genomes have been indi...

The determination of the antioxidant potential of lyophilized mushroom mycelia from 5 strains of the species Pleurotus ostreatus and Coprinus comatus (obtained by submerged cultivation in batch system) was analyzed as ethanolic extracts by evaluating ABTS and the hydroxyl scavenging activity, FRAP method, the chelating capacity, the inhibition of human erythrocyte hemolysis, and the inhibition ...

The detoxification of Jatropha curcas seed cake is of major interest for the biodiesel industry to add economic value to this residue and also to reduce the environmental damage caused by its inappropriate disposal. In this context, the treatment of this residue with white rot fungus, Pleurotus ostreatus, can be a viable alternative because it produces enzymes capable of degrading different lig...
