Use of sugarcane molasses by Pycnoporus sanguineus for the production of laccase for dye decolorization.
Pycnoporus sanguineus is a white-rot basidiomycete that produces laccase as the only oxidoreductase; enzyme synthesis depends on cultivation variables, and fungal species and strain. Laccases have wide substrate specificity, oxidize a broad range of compounds, and show potential for use in dye decolorization. We evaluated laccase production in a recently isolated strain of P. sanguineus cultiva...
متن کاملTitle Optimization of laccase production by Pycnoporus sanguineus in submerged liquid culture
The white-rot fungus Pycnoporus sanguineus produces laccase under a range of C/N ratios in submerged liquid culture. Enzyme production was increased 50 fold in the presence of 20 FM xylidine to a maximum of 1368 U L-I in a high carbon low nitrogen medium. Slight repression of enzyme production was observed in high nitrogen culture medium. Other potential inducers were less effective (Tween 80, ...
متن کاملEffect of different wavelengths of light on laccase, cellobiose dehydrogenase, and proteases produced by Cerrena unicolor, Pycnoporus sanguineus and Phlebia lindtneri.
Three species of white rot fungi: Cerrena unicolor, Phlebia lindtneri and Pycnoporus sanguineus were cultured in two different media under five different lighting conditions: dark, white, red, blue, and green light. Laccase, cellobiose dehydrogenase, and protease activities were examined in the samples. Blue light efficiently boosted laccase synthesis in C. unicolor and P. sanguineus, whereas t...
متن کاملProduction of laccase by Pynoporus sanguineus using 2,5 - Xylidine and ethanol
Enzyme application in biotechnological and environmental processes has had increasing interest due to its efficiency, selectivity and mainly for being environmentally healthful, but these applications require a great volume of enzymes. In this work the effect of different concentrations of ethanol and 2,5-xylidine on growth and production of laccase by Pycnoporus sanguineus was investigated. In...
متن کاملA High Redox Potential Laccase from Pycnoporus sanguineus RP15: Potential Application for Dye Decolorization
Laccase production by Pycnoporus sanguineus RP15 grown in wheat bran and corncob under solid-state fermentation was optimized by response surface methodology using a Central Composite Rotational Design. A laccase (Lacps1) was purified and characterized and the potential of the pure Lacps1 and the crude culture extract for synthetic dye decolorization was evaluated. At optimal conditions (eight ...
