| exophiala crusticola anam. nov. (affinity herpotrichiellaceae), a novel black yeast from biological soil crusts in the western united states. | a novel black yeast-like fungus, exophiala crusticola, is described based on two closely related isolates from biological soil crust (bsc) samples collected on the colorado plateau (utah) and in the great basin desert (oregon), usa. their morphology places them in the anamorphic genus exophiala, having affinities to the family herpotrichiellaceae (ascomycota). phylogenetic analysis of their d1/d2 large subunit nuclear ribosomal rna (lsu nrrna) gene sequences suggests that they represent a distin ... | 2006 | 17082414 |
| black yeast diversity on creosoted railway sleepers changes with ambient climatic conditions. | the environmental isolation of opportunistic pathogenic black yeasts, which are responsible for a wide spectrum of human infections, is essential to understanding the ecology of clinical fungi. extreme outdoor environments polluted with aromatic hydrocarbons support the growth of black yeasts in unlikely places, such as railway sleepers. however, there are limited data concerning the diversity of these fungi growing on polluted railway sleepers. in this investigation, we examined 845 railway sle ... | 2014 | 25027275 |
| black yeast habitat choices and species spectrum on high altitude creosote-treated railway ties. | polyextremotolerant black yeast-like fungi thrive in moderately hostile environments where they are concomitantly subjected to several types of stress, such as toxicity, scarce nutrient availability, and high or low temperature extremes. their ability to assimilate alkylbenzenes (toxic environmental pollutants) enhances their growth in harsh conditions, including on railway ties. samples were collected using cotton swabs, premoistened with physiological saline, from 658 oak and concrete railway ... | 2013 | 24119407 |
