exophiala sideris, a novel black yeast isolated from environments polluted with toxic alkyl benzenes and arsenic. | a novel species of the black yeast genus exophiala (order chaetothyriales) is described. strains were repeatedly obtained by enriching samples of wild berries from different plants, guano-rich soil and from oak railway ties treated with arsenic creosote under a toluene-rich atmosphere. an identical strain was encountered in a closed arsenic mine polluted by alkyl benzenes. its potential use for purposes of bioremediation is discussed. | 2011 | 21944215 |
