Abstract
Four strains of two novel xylose-utilizing yeast species were obtained from samples collected in Thailand from decaying corncobs (strains KU-Xs13(T) and KU-Xs18), a decaying grass (KU-Xs20) and estuarine water from a mangrove forest (WB15(T)). On the basis of morphological, biochemical, physiological and chemotaxonomic characteristics and sequence analysis of the D1/D2 domain of the large subunit rRNA gene, the four strains were found to represent two novel species of the genus Candida in the Candida albicans/Lodderomyces elongisporus clade. Three strains (KU-Xs13T, KU-Xs18 and KU-Xs20) were assigned as a single novel species, which was named Candida saraburiensis sp. nov. The type strain is KU-Xs13(T) (=CBS 11696(T)=NBRC 106721(T)=BCC 39601(T)). Strain WB15(T) represented another novel species of the genus Candida that was named Candida prachuapensis sp. nov. The type strain is WB15(T) (=CBS 11024(T)=NBRC 104881(T)=BCC 29904(T)).
