A Novel Heterothallic Ascomycetous Yeast Species: Stephanoascus smithiae, Teleomorph of Candida edax

A phylogenetic study on galactose-containing Candida species based on 18S ribosomal DNA sequences.

“…chiloensis (Meyer et al, 1998). They were related to C. edax (anamorph of Stephanoascus smithiae) (Giaménez-Jurado et al, 1994), and linked to C. steatolytica (synonym of Zygoascus hellenicus) and Arxula adeninivorans. The second subgroup consisted of C. santjacobensis, and it was connected to A. terrestris, the type species of the anamorphic genus Arxula (van der Walt et al, 1990), which contains galactose in the cells (Weijman, 1979).…”

Diversity of the genus Sugiyamaella and description of two new species from rotting wood in China

“…Sugiyamaella Kurtzman & Robnett (2007) is typified by Sugiyamaella smithiae, which was initially classified in the genus Stephanoascus (Giménez-Jurado et al 1994). The genus Sugiyamaella belongs to the family Trichomonascaceae in the order Saccharomycetales and is closely related to the genera Trichomonascus, Wickerhamiella and Zygoascus, based on multigene phylogenetic analyses of LSU, MtSm and COXII nucleotide sequences (Kurtzman and Robnett 2007;Péter et al 2012 ).…”

Candida tartarivorans sp. nov., an anamorphic ascomycetous yeast with the capacity to degrade L(+)- and meso-tartaric acid.

“…2). A possible relationship between these species and others that share the ability to assimilate inositol had been previously suggested based on the comparative analysis of phenotypic characteristics (Fonseca, 1992 ;Gime! nez-Jurado et al, 1994).…”

“…We found that the capacity to degrade tartaric acid, and other related aldaric acids, occurs mainly in yeasts of basidiomycetous affinity and very rarely among ascomycetous yeasts (Fonseca, 1992(Fonseca, , 1995. The only ascomycetous species that showed the ability to assimilate tartaric acid were Candida bertae, Candida paludigena and Stephanoascus smithiae, which appear to be closely related based on phenotypic (Fonseca, 1992 ;Gime! nez-Jurado et al, 1994) and genotypic (Kurtzman & Robnett, 1995, 1997, 1998 selective media with (j)-tartaric acid (Fonseca, 1992), we isolated a strain of ascomycetous affinity from dried wine lees, which could not be identified as any previously described species according to morphological and physiological characteristics (Barnett et al, 1990 ;Kurtzman & Fell, 1998 …”
