Abstract

Two previously undescribed anamorphic yeasts, strains T-11 and T-26, recovered from wild rabbit faecal pellets collected in Muju, Korea, were identified using phenotypic and molecular taxonomic methods. The isolates were characterized by the proliferation of budding cells, positive diazonium blue B and urease reactions, the presence of Q-10 as the major ubiquinone, the presence of xylose in whole-cell hydrolysates and the inability to ferment sugars. Phylogenetic analyses based on 26S rRNA gene partial sequences revealed that strain T-11 was located in the clade and was related to , , and . Strain T-26 was located in the Mesenterica clade and was closely related to sp. F6 and CBS 8976. Sequence divergence values of more than 4 % from other described species, together with the phenotypic differences, showed that the isolated yeasts represent previously unrecognized members of this genus. Therefore, two novel yeast species are proposed: sp. nov., with strain T-11 (=KCTC 17231=CBS 10308) as the type strain, and sp. nov., with strain T-26 (=KCTC 17232=CBS 10309) as the type strain.
