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...

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...

Microbial silver nanoparticles have been known to have bactericidal effects but the antimicrobial mechanism have not been clearly revealed. The use of microorganisms in the synthesis of nanoparticles emerges as an ecofriendly and exciting approach. In this study biosynthesis of silver nanoparticles using Pleurotus sajor caju fungi and its antimicrobial studies has been reported. The extra cellu...

BACKGROUND Pleurotus sajor-caju (P. sajor-caju) has been extremely useful in the prevention of diabetes mellitus due to its low fat and high soluble fiber content for thousands of years. Insulin resistance is a key component in the development of diabetes mellitus which is caused by inflammation. In this study, we aimed to investigate the in vivo efficacy of glucan-rich polysaccharide of P. saj...

different competitor weed fungi rhizopus stolonifer, penicillium glabrum, fusarium oxysporum and coprinopsis kimurae were found to have associated with the fruit beds as constant contaminants of pleurotus sajor-caju and lentinula edodes. several antagonists, plant extracts and chemicals were tested against the weed fungi to screen the most effective ones and to have an integrated combination fo...

A preliminary investigation was conducted to assess lignocellulolytic efficiency of crude extracts from three white-rot fungi, Pleurotus florida PF05 (PF), Pleurotus sajor-caju PS07 (PS) and Pleurotus eryngii PE08 (PE). The activities of CMC-ase, xylanase, beta-glucosidase, beta-xylosidase, laccase and Mn peroxidase in extracts were evaluated. PF produced its highest CMC-ase (317 UL(-1)'), beta...
