Saccharomyces jurei sp. nov., Isolation and Genetic Identification of a Novel Yeast Species from Quercus robur.. Saccharomyces jurei sp. nov., Isolation and Genetic Identification of a Novel Yeast Species from Quercus robur.

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 1000m above sea level in Saint Auban, France. Sequence analyses of the internal transcribed spacer (ITS) region and 26S rDNA D1/D2 domains indicated that the two strains were most closely related to S. mikatae and S. 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.
