    Abstract

    Two strains (NT29T and NT31T) of xylose-assimilating yeasts were obtained from soils collected in northern Thailand. On the basis of morphological, biochemical, physiological and chemotaxonomic characteristics, and sequence analysis of the D1/D2 domain of the large subunit rRNA gene and the internal transcribed spacer region, the two strains were found to represent two novel ascomycete yeast species. Strain NT29T was assigned to the genus Candida belonging to the Pichia clade as a representative of Candida phayaonensis sp. nov.; the type strain is NT29T ( = BCC 47634T = NBRC 108868T = CBS 12319T). Strain NT31T represented a novel Wickerhamomyces species, which was named Wickerhamomyces xylosica sp. nov.; the type strain is NT31T ( = BCC 47635T = NBRC 108869T = CBS 12320T).

    • The GenBank/EMBL/DDBJ accession numbers for the sequence of the D1/D2 domain of the LSU rRNA gene/ITS regions of strains NT29T and NT31T are AB557865/AB704714 and AB557867/AB704715, respectively.
