White rot fungi have one of the most efficient oxidative lignin degradation systems, and present an enzymatic complex that is responsible for digesting lignocellulosic matter. The aim this study was to evaluate production laccase total peroxidases by Ganoderma lucidum via solid-state fermentation using açaí seeds marupá (Simarouba amara) sawdust unsupplemented supplemented with wheat, corn rice...

Aim: The aims of the present study were to screen different filamentous fungi for extracellular cellulases production and to optimize solid-state fermentation medium and culture conditions to enhance cellulases production. Study Design: Using agro-industrial waste as raw material for the production of cellulases by a hyper cellulase producing fungus and evaluating the influence of various param...

Lignin is a major component of soil organic matter and also a rich source of carbon dioxide in soils. However, because of its complex structure and recalcitrant nature, lignin degradation is a major challenge. Efforts have been made from time to time to understand the lignin polymeric structure better and develop simpler, economical, and bio-friendly methods of degradation. Certain enzymes from...

Effluents containing dyes from different industrial sectors pose a serious threat to the environment. Different physicochemical strategies are being carried out in industry reduce toxicity of dye-containing waste so that dye-mixed wastewater can be further utilized agriculture or irrigation purposes water-scarce areas. But those techniques economically not feasible. There is an alternative mech...

A novel strain of Bjerkandera sp. (B33/3), with particularly high decolourisation activities upon Poly R-478 and Remazol Brilliant Blue R (RBBR) dyes, was isolated. The role of the ligninolytic extracellular enzymes produced by this strain on decolourisation of RBBR was studied in some depth. The basis of decolourisation is an enzyme-mediated process, in which the main enzyme responsible is a r...

White-rot basidiomycetes are the only microorganisms with ability to produce both hydrolytic (cellulases and hemicellulases) oxidative (ligninolytic) enzymes for degrading cellulose/hemicellulose lignin. In addition, they biologically active natural products important application in cosmetic formulations, either as pure compounds or standardized extracts. present work, three wild strains of Bas...

Remazol Brilliant Blue R (RBBR) dye was used as substrate to evaluate ligninolytic activity in 125 basidiomycetous fungi isolated from tropical ecosystems. The extracellular RBBR decolorizing activity produced when selected fungi were grown in solid media and in soil contaminated with organochlorines was also evaluated. A total of 106 fungi decolorized the RBBR during the growth in malt extract...

The versatile-peroxidase (VP) encoded by mnp4 is one of the nine members of the manganese-peroxidase (MnP) gene family that constitutes part of the ligninolytic system of the white-rot basidiomycete Pleurotus ostreatus (oyster mushroom). VP enzymes exhibit dual activity on a wide range of substrates. As Mn(2+) supplement to P. ostreatus cultures results in enhanced degradation of recalcitrant c...
