Abstract

Two novel yeast species, sp. nov. and sp. nov., belonging to the Saccharomycetaceae within the Saccharomycetales, are proposed to accommodate six strains isolated from samples of Taiwanese forest soil between 2005 and 2010. Sequence analysis of the internal transcribed spacer (ITS) and the D1/D2 domains of the large-subunit (LSU) rRNA gene revealed that the two species are phylogenetically closely related to species of the genus . Moreover, the assimilation spectrum of carbon and nitrogen sources and morphological characteristics are very similar to those of other species. The molecular, morphological and physiological characteristics described above indicate that these two species should be classified as members of the genus . The two species can be differentiated from each other and from other species based on their LSU D1/D2 rRNA gene and ITS sequences. Thus, the two species could be regarded as novel species of the genus , and the names sp. nov. (type strain SJ6S04  = CBS 10586  = NBRC 102652  = BCRC 23090) and sp. nov. (type strain NC2S06  = CBS 12780  = BCRC 23409) are proposed. The type strains of the two species were isolated from forest soil in Leinhuatsu Park, Nantou, in 2006 and from Hungchun, Pingtung, in 2009, respectively.
