The aim of this study was to enumerate and identify yeasts present in Greek kefir. Total yeast counts in kefir grains were 7.7 ± 0.5 log cfu/g, whereas in kefir drinks counts ranged from <0.4 to 6.7 log cfu/mL. Molecular identification tests revealed 14 different yeast species belonging to 10 genera (Candida spp., Debaryomyces spp., Galactomyces spp., Issatchenkia spp., Kazachstania spp., Kluyveromyces spp., Pichia spp., Saccharomyces spp., Wickerhamomyces spp., Yarrowia spp.). This study is the first to identify yeast species present in Greek kefirs and to isolate Pichia membranifaciens and Candida zeylanoides as part of the kefir microbiota.
