OBJECTIVE To report a patient with severe Chrysosporium keratitis successfully treated by voriconazole. METHOD Case report. RESULTS A 37-year-old healthy male presented with irritation, pain and reduced vision in his left eye after mud contamination. Examination demonstrated corneal stromal infiltration, endothelial plaque and hypopyon. Corneal scrapings demonstrated numerous septate hyphae...

A 50-year-old woman who gardens regularly with rotting bark mulch presented with exertional dyspnea, diffusion impairment, and radiographic abnormalities (centrilobular nodules, tree-in-bud and ground glass opacities, calcified mediastinal and hilar lymph nodes) on a computed tomogram. Moderate lymphocytosis was noted on bronchoalveolar lavage. Surgical biopsy of her lung revealed granulomatous...

A selective medium was developed that is capable of isolating Phanerochaete chrysosporium from soil. This medium contains 15 ppm of benomyl (15 mug g) and 550 ppm of streptomycin sulfate in 2% malt agar and is held at 39 degrees C after inoculation. P. chrysosporium was isolated from three nonsterile forest soils to which the fungus had been added. These soils contained large microbial populati...

Plant biomass can be utilized by a lignocellulose-degrading fungus, Phanerochaete chrysosporium, but the metabolic and regulatory mechanisms involved are not well understood. A polyomics-based analysis (metabolomics, proteomics, and transcriptomics) of P. chrysosporium has been carried out using statistically optimized conditions for lignocellulolytic reaction. Thirty-nine metabolites and 123 g...

Pyranose 2-oxidase (POX) was recovered from Phanerochaete chrysosporium BKM-F-1767 solid substrate culture using mild extraction conditions and was purified. (13)C-nuclear magnetic resonance confirmed production of d-arabino-hexos-2-ulose (glucosone) from d-glucose with the oxidase. Peptide fingerprints generated by liquid chromatography-tandem mass spectrometry of tryptic digests and analysis ...

Twenty-two azo dyes were used to study the influence of substituents on azo dye biodegradability and to explore the possibility of enhancing the biodegradabilities of azo dyes without affecting their properties as dyes by changing their chemical structures. Streptomyces spp. and Phanerochaete chrysosporium were used in the study. None of the actinomycetes (Streptomyces rochei A10, Streptomyces ...

Four isozymes of manganese peroxidase (MnP) were identified in the culture fluid of the hyperlignolytic fungus IZU-154 under nitrogen starvation conditions. One of them was purified and characterized kinetically. The specific activity and Kcat/K(m) value of the MnP from IZU-154 were 1.6 times higher than those of the MnP from a typical lignin-degrading fungus, Phanerochaete chrysosporium. Two c...

Of 18 commercially used textile dyes, eight were degraded by the white rot fungus,Phanerochaete chrysosporium, by 40 to 73% based on decrease of colour. Both the lignin-degrading enzyme system ofP. chrysosporium and adsorption to its cell mass were involved in the degradation of the diazo dye, Reactofix Gold Yellow. Degradation was best achieved by adding the dye to the medium and then inoculat...

Heterokaryons made from auxotrophic strains of the lignin-degrading basidiomycete Phanerochaete chrysosporium were induced to fruit. The isolation of wild-type and double-mutant phenotypes from these crosses indicated that genetic recombination had occurred. Cytological studies demonstrated that more than 90% of the basidiospores from the wild-type and auxotrophic strains and from forced hetero...

A 1747-bp insertion within a lignin peroxidase allele of Phanerochaete chrysosporium BKM-F-1767 is described. Pce1, the element, lies immediately adjacent to the fourth intron of lip12. Southern blots reveal the presence of Pce1-homologous sequences in other P. chrysosporium strains. Transposon-like features include inverted terminal repeats and a dinucleotide (TA) target duplication. Atypical ...
