Four ascomycetous yeast strains (D4W13, D9W2, D9W4 and D9W17) were isolated from -affected fermenting grape juice originating from Attica Province, Greece. Phylogenetic analysis of rRNA gene sequences (18S, 26S and 5.8S–ITS) showed that the four strains represent a distinct species within the genus , closely related to NBRC 100504 and NBRC 11056. Electrophoretic karyotyping and physiological analysis support the affiliation of the four strains in a novel species for which the name sp. nov. is proposed, with D9W17 (=CBS 10706=NBRC 103637) as the type strain.
