Isolated and identified yeast species in wines of grapes from Turkey were compared with those from other countries. The wild yeasts from five different grape varieties were detected by real-time PCR and isolated/identified by DNA sequencing techniques. Totally 469 yeast colonies were isolated from selective media at different times from musts and wine samples. 104 from 204 non-Saccharomyces and 47 from 265 Saccharomyces yeast isolates selected based on colony morphology or physiological characteristics were identified using DNA sequencing by internal transcribed spacer (ITS) region (ITS1{\textendash}5.8S rRNA{\textendash}ITS2). Nine non-Saccharomyces yeast species belonging to seven genera: Starmerella bacillaris (syn., Candida zemplinina), Hanseniaspora species (H. guilliermondii, H. opuntiae, H. uvarum), Rhodotorula mucilaginosa, Wickerhamomyces anomalus (syn., Pichia anomala), Lachancea thermotolerans, Solicoccozyma aeria, Metschnikowia spp., and Saccharomyces cerevisiae were identified according to sequencing results. Results were concordant with the results of the real-time PCR. However, several species were only detected by real-time PCR. Further analysis on strains of non-Saccharomyces species was carried out to construct phylogenetic tree.}, issn = {0002-9254}, URL = {https://www.ajevonline.org/content/early/2022/06/30/ajev.2022.22001}, eprint = {https://www.ajevonline.org/content/early/2022/06/30/ajev.2022.22001.full.pdf}, journal = {American Journal of Enology and Viticulture} }
