| trichosporon xylopini sp. nov., a hemicellulose-degrading yeast isolated from wood-inhabiting beetle xylopinus saperdioides. | four arthroconidium-producing yeasts were isolated from the gut of wood-inhabiting tenebrionid and passalid beetles. the ribosomal rna genes of these yeast strains were sequenced, compared and analyzed. the sequence results and other taxonomic characterizations placed two of the strains into trichosporon porosum, and the remaining strains, eh024 and eh026 which were isolated from xylopinus saperdioides (coleoptera: tenebrionidae), to a novel trichosporon species in the porosum clade. strain en6s ... | 2010 | 21037034 |
| production of antifungal cellobiose lipids by trichosporon porosum. | the yeast trichosporon porosum suppresses growth of ascomycetes and basidiomycetes belonging to 52 genera. it is due to secretion of a thermostable fungicidal agent. the suppression was maximal at ph 3.5-4.0. fungicidal preparation obtained from the culture broth was shown to be a mixture of cellobiosides of dihydrodecane acid with different degree of acetylation of cellobiose residue. the preparation caused the death of candida albicans and filobasidiella neoformans cells in the concentrations ... | 2010 | 19757153 |
| polysaccharides and phenolic compounds as substrate for yeasts isolated from rotten wood and description of cryptococcus fagi sp.nov. | pieces of rotten wood collected in the forest were screened for the presence of yeasts. in spring time 3 tree species were sampled, followed by 9 species in summer. yeast strains were identified by traditional methods. identifications were confirmed by sequencing of ribosomal dna in case of doubt. in total 14 yeast species of ascomycetous affiliation and 6 anamorphic basidiomycetous yeasts were isolated and identified. most species were represented by only one strain, but candida bertae by two a ... | 2006 | 16652205 |
| trichosporon porosum comb. nov., an anamorphic basidiomycetous yeast inhabiting soil, related to the loubieri/laibachii group of species that assimilate hemicelluloses and phenolic compounds. | several isolates representing the genus trichosporon were collected over a 6-year period from soils in the netherlands. based on classical growth tests with carbon and nitrogen compounds these were identical. three of these (cbs 8396, cbs 8397 and cbs 8522) were subjected to molecular analysis of the d1/d2 region of the large subunit of rdna. this confirmed that the three strains were identical, yet distinct from other members of the genus. conspecificity was demonstrated with the type strain (c ... | 2001 | 12702459 |
