| cryptoporic and isocryptoporic acids from the fungal cultures of polyporus arcularius and p. ciliatus. | in a chemical study of several fungal cultures of polyporus, a methyl ester of cryptoporic h was isolated from p. ciliatus, together with cryptoporic acid h and 5-hydroxymethylfuran-3-carboxylic acid. furthermore, two additional compounds, named isocryptoporic acids h and i, were isolated from p. arcularius. these isocryptoporic acids are isomers of the cryptoporic acids with drimenol instead of albicanol as the terpenoid fragment; their structural elucidation was determined by application of sp ... | 2002 | 12169314 |
| biodegradation of wood in dual cultures of selected two fungi determined by chopstick method. | wood was more effectively degraded in dual cultures of pycnoporus coccineus with either flammulina velutipes, pleurotus ostreatus or polyporus arcularius than in their single cultures based on the weight losses of chopsticks. the similar effects were attained in dual cultures of the selected basidiomycetes and various soil fungi. | 2003 | 16233468 |
| transcriptional regulation of two endoglucanase-encoding genes (cel3a and cel4) from the wood-degrading basidiomycete polyporus arcularius. | in the current study, the genomic and cdna clones encoding the endoglucanase (cel4) of polyporus arcularius were sequenced and characterized. the amino acid sequence of cel4 indicated that it is a glycosyl hydrolase family 5 protein. the expressions of the previously cloned endoglucanase cel3a and cel4 were induced by avicel (microcrystalline cellulose) and cellopentaose but repressed by glucose, cellobiose, cellotriose, and cellotetraose. there was a low level of transcription of both genes reg ... | 2007 | 17608693 |
| transcriptional regulation of two cellobiohydrolase encoding genes (cel1 and cel2) from the wood-degrading basidiomycete polyporus arcularius. | in the current studies, we sequenced and characterized the genomic and complementary deoxyribonucleic acid clones encoding the cellobiohydrolase encoding genes cel1 and cel2 of polyporus arcularius. the predicted amino acid sequences of cel1 and cel2 are similar to glycosyl hydrolase family 7 and 6 proteins, respectively. the expression of cel1 and cel2 was induced by microcrystalline cellulose (avicel) and cellopentaose but repressed by glucose, cellobiose, cellotriose, and cellotetraose. there ... | 2007 | 17641888 |
| selection of newly isolated mushroom strains for tolerance and biosorption of zinc in vitro. | nine newly isolated mushroom strains were tested to assess both their zinc tolerance and potential for zinc removal from an aqueous solution. four strains of ectomycorrhizal fungi, namely clavariadelphus truncatus (t 192), rhizopogon roseolus (t 21), lepista nuda (t 373), and tricholoma equestre (t 174), along with five strains of white rot fungi, lenzites betulina (s 2), trametes hirsuta (t 587), ganoderma spp. (t 99), polyporus arcularius (t 438), and ganoderma carnosum (m 88), were investigat ... | 2008 | 18388466 |
| first synthesis of (+/-)-basidifferquinone c, an inducer for fruiting-body formation in polyporus arcularius. | basidifferquinones, isolated from streptomyces sp., are potent inducers of fruiting-body formation in the basidiomycete, polyporus arcularius. the first synthesis of (+/-)-basidifferquinone c was accomplished by starting from 3,5-dihydroxy-2-naphthoic acid. | 2009 | 19809187 |
| new fungal biomasses for cyanide biodegradation. | cyanide, a hazardous substance, is released into the environment as a result of natural processes of various industrial activities which is a toxic pollutant according to environmental protection agency. in nature, some microorganisms are responsible for the degradation of cyanide, but there is only limited information about the degradation characteristics of basidiomycetes for cyanide. the aim of the present study is to determine cyanide degradation characteristics in some basidiomycetes strain ... | 2010 | 20547364 |
