Yeasts Isolated from the Alcoholic Fermentation ofAgave duranguensisDuring Mezcal Production

Mezcal is a spirit produced in some regions of Mexico. In the state of Durango, mezcal is produced via traditional fermentation of the Agave duranguensis plant. To better understand traditional fermentation processes, it is necessary to know which yeast species are present in fermentations in different producer regions. The aim of this research was to study yeasts involved in traditional mezcal fermentation in Durango, Mexico, and investigate the phylogeny of the native Saccharomyces cerevisiae strains involved in this process. The 5.8S-ITS genomic region was analyzed to identify strains present in the fermentation process samples in this study. To differentiate strains belonging to the gen…
