Two strains, D5088T and D5095, representing a novel yeast species belonging to the genus Saccharomyces were isolated from oak tree bark and surrounding soil located at an altitude of 1000 m above sea level in Saint Auban, France. Sequence analyses of the internal transcribed spacer (ITS) region and 26S rRNA D1/D2 domains indicated that the two strains were most closely related to Saccharomyces mikatae and Saccharomyces paradoxus. Genetic hybridization analyses showed that both strains are reproductively isolated from all other Saccharomyces species and, therefore, represent a distinct biological species. The species name Saccharomyces jurei sp. nov. is proposed to accommodate these two strains, with D5088T (=CBS 14759T=NCYC 3947T) designated as the type strain.
从法国圣欧班海拔1000米处的橡树树皮及周围土壤中分离出了两个菌株，D5088T和D5095，它们代表了酿酒酵母属的一个新酵母物种。对内部转录间隔区（ITS）区域和26S rRNA D1/D2结构域的序列分析表明，这两个菌株与日本酿酒酵母和奇异酿酒酵母关系最为密切。遗传杂交分析表明，这两个菌株与所有其他酿酒酵母物种在生殖上是隔离的，因此代表一个独特的生物物种。提议将这两个菌株归为酿酒酵母新种（Saccharomyces jurei sp. nov.），并指定D5088T（=CBS 14759T=NCYC 3947T）为模式菌株。
