"The present work aimed to study how factors such as carbon and nitrogen source, calcium and magnesium concentration (in the medium), aeration or temperature disturb the metabolism of non-Saccharomyces yeasts (Kluyveromyces marxianus and Pichia kluyveri), specifically their impact on the production of volatile compounds during alcoholic fermentation of agave must employed in Tequila elaboration process. The used yeasts were obtained from the collection of CIATEJ strains, which were isolated from artisanal mezcal fermentation processes from the states of Oaxaca, Guerrero and San Luis Potosi in Mexico. It is intended to use the information generated and then using these yeasts in alcoholic fermentation processes for the production of tequila. Based on prior knowledge that non-Saccharomyces yeasts are good producers of volatile compounds desired in alcoholic beverages requested by consumers and the results of this study, the use of these strains is considered for tequila production. The results obtained in the present study revealed that all tested factors disturbed volatile compound production in these non-Saccharomyces yeasts and therefore need to be considered to drive fermentation processes aiming the production of a more aromatic beverage. Some yeast strains showed good potential to perform fermentation without or in co-culture with S. cerevisiae obtaining in both cases a product with more desired flavors compared to products currently on the market. The knowledge about the physiological needs of these yeasts gives the opportunity to modify the composition of the alcoholic beverage, only by controlling the parameters during the fermentation process" | |
