Two isolates representing a new species of Scheffersomyces were isolated from rotting wood samples collected in an Amazonian forest ecosystem in Brazil. Analysis of the sequences of the D1/D2 domains showed that this new species is phylogenetically related to Scheffersomyces NYMU 15730, a species without a formal description, and the two are in an early emerging position with respect to the xylose-fermenting subclade containing Scheffersomyces titanus and Scheffersomyces stipitis. Phylogenomic analyses using 474 orthologous genes placed the new species in an intermediary position between Scheffersomyces species and the larger genus Spathaspora and the Candida albicans/Lodderomyces clade. The novel species, Scheffersomyces stambukii f.a., sp. nov., is proposed to accommodate these isolates. The type strain of Scheffersomyces stambukii sp. nov. is UFMG-CM-Y427 (=CBS 14217). The MycoBank number is MB 824093. In addition, we studied the xylose metabolism of this new species.
从巴西亚马逊森林生态系统采集的腐烂木材样本中分离出了两个代表新种Scheffersomyces的菌株。对D1/D2结构域序列的分析表明，这个新物种在系统发育上与Scheffersomyces NYMU 15730相关，后者是一个未正式描述的物种，并且这两个物种在包含Scheffersomyces titanus和Scheffersomyces stipitis的木糖发酵亚分支中处于早期出现的位置。使用474个直系同源基因进行的系统基因组分析将这个新物种置于Scheffersomyces物种与更大的Spathaspora属以及白色念珠菌/ Lodderomyces进化枝之间的中间位置。提议用新种Scheffersomyces stambukii f.a., sp. nov.来容纳这些菌株。Scheffersomyces stambukii sp. nov.的模式菌株是UFMG-CM-Y427 (=CBS 14217)。其国际真菌命名数据库编号为MB 824093。此外，我们研究了这个新物种的木糖代谢。
