Graphene has been used in various applications many fields. In recent years, its annual output reached one hundred tons. shown great potential analytics, medicine, electronics, energy, agriculture, and environmental remediation. With increasing production, the risks hazards of graphene have increased public concern. It was a key issue risk assessments materials. Microbial degradation oxide by f...

Untreated pharmaceutical pollution and their possibly toxic metabolites, resulting from overloaded wastewater treatment processes, end up in aquatic environments are hazardous to the ecosystem homeostasis. Biological remediation could supplement traditional methods overcome release of these biologically active compounds environment. Mycoremediation is especially promising due unspecific nature ...

Under nitrogen-limiting, secondary metabolic conditions, the white rot basidiomycete Phanerochaete chrysosporium extensively mineralized the specifically 14C-ring-labeled azo dyes 4-phenylazophenol, 4-phenylazo-2-methoxyphenol, Disperse Yellow 3 [2-(4'-acetamidophenylazo)-4-methylphenol], 4-phenylazoaniline, N,N-dimethyl-4-phenylazoaniline, Disperse Orange 3 [4-(4'-nitrophenylazo)-aniline], and...

mRNA extraction from soil and quantitation by competitive reverse transcription-PCR were combined to study the expression of three manganese peroxidase (MnP) genes during removal of polycyclic aromatic hydrocarbons from cultures of Phanerochaete chrysosporium grown in presterilized soil. Periods of high mnp transcript levels and extractable MnP enzyme activity were temporally correlated, althou...

mRNA extraction from soil and quantitation by competitive reverse transcription-PCR were combined to study the expression of the 10 known lignin peroxidase (lip) genes in anthracene-transforming soil cultures of Phanerochaete chrysosporium. Levels of extractable lipA transcript and protein (LiP H8) were well correlated, although they were separated by a 2-day lag period. The patterns of transcr...

Glutathione transferases (GSTs) form a superfamily of multifunctional proteins with essential roles in cellular detoxification processes and endogenous metabolism. The distribution of fungal-specific class A GSTs was investigated in saprotrophic fungi revealing a recent diversification within this class. Biochemical characterization of eight GSTFuA isoforms from Phanerochaete chrysosporium and ...

This study examined the ligninase-catalysed degradation of lignin model compounds representing the arylglycerol ,-aryl ether substructure, which is the dominant one in the lignin polymer. Three dimeric model compounds were used, all methoxylated in the 3and 4-positions of the arylglycerol ring (ring A) and having various substituents in the ,-ether-linked aromatic ring (ring B), so that competi...

The cDNA of endo-1,4-β-xylanaseA, isolated from Phaenerocheate chrysosporium was expressed in Pichia pastoris. Using either the intrinsic leader peptide of XynA or the α-factor signal peptide of Saccharomyces cerevisiae, xylanaseA is efficiently secreted into the medium at maximum concentrations of 1,946 U/L and 2,496 U/L, respectively.

Prevalence of keratinophilic fungi was observed in paddy field soil during different stages of cultivation viz., transplanting, tillering, milking and maturation. Out of total 76 soil samples, 65 soil samples were found to be positive for the keratinophilic fungi. Fourteen species belonging to a single genus Chrysosporium were isolated through out the cropping season. C. keratinophilum (17.1%) ...
