Abstract

The abundant variety of yeasts and their diverse applications have essential roles in traditional Mexican alcoholic beverage fermentation processes. During our investigation of yeast diversity associated with Pulque, 41 yeast strains were characterized. Among them, 31 strains were eight known species belonging to seven genera. According to morphological and phylogenetic analyses (ITS and LSU rDNA), ten unidentified yeast strains were identified to be three novel species and proposed: Starmerella elongatumsp. nov., Kazachstania paragamosporasp. nov. and Pichia teotihuacanensissp. nov. Our study has resulted in the isolation of yeast species not previously detected in Pulque, expanding our knowledge of the diversity of its associated yeast communities.
