Abstract

Abstract : Three strains, representing a novel anamorphic and d -xylose-fermenting yeast species, were isolated from moss (ST-302 T ), seawater (ST-1169) and peat (DMKU-XE12) collected from the southern part of Thailand. The three strains had identical sequences of the D1/D2 regions of the large subunit (LSU) rRNA gene and the internal transcribed spacer (ITS) regions. Candida flosculorum CBS 10566 T and Candida sharkiensis CBS 11368 T were the most closely related species with 7.9 % nucleotide substitutions in the D1/D2 regions of the LSU rRNA gene, and 10.3 and 12.6% nucleotide substitutions in the ITS regions, respectively. Phylogenetic analysis based on the concatenated sequences of the ITS and the D1/D2 regions confirmed that the three strains represented a distinct anamorphic species in the Clavispora clade. Therefore, the three strains were described as a novel species, for which we propose the name Candida xylosifermentans sp. nov.
