Application of Non-Saccharomyces Yeasts to Wine-Making Process
Winemaking is a complex process involving the interaction of different microbes. The two main groups of microorganisms involved are yeasts and bacteria. Non-Saccharomyces yeasts are present on the grape surface and also on the cellar. Although these yeasts can produce spoilage, these microorganisms could also possess many interesting technological properties which could be exploited in food pro...
متن کاملEnzyme Contribution of Non-Saccharomyces Yeasts to Wine Production
The fermentation of grape must to produce wine is a biologically complex process, carried on by yeasts and malolactic bacteria. The yeasts present in spontaneous fermentation may be divided into two groups, the Saccharomyces yeasts, particularly S. cerevisiae, and the non-Saccharomyces yeasts which include members of the genera Rhodotorula, Pichia, Candida, Debaryomyces, Metschtnikowia, Hansenu...
متن کاملImprovement of wine organoleptic characteristics by non-Saccharomyces yeasts
In traditional winemaking, natural fermentation of grape juice is carried out by a sequence of different yeast species. The early stages are dominated by non-Saccharomyces yeasts and are replaced by Saccharomyces cerevisiae that finish the fermentation process. In this chapter was evaluated the kinetics and metabolic behavior of Kloeckera apiculata mc1 and S. cerevisiae mc2 in composite culture...
متن کاملCellular death of two non-Saccharomyces wine-related yeasts during mixed fermentations with Saccharomyces cerevisiae.
The early death of two non-Saccharomyces wine strains (H. guilliermondii and H. uvarum) during mixed fermentations with S. cerevisiae was studied under enological growth conditions. Several microvinifications were performed in synthetic grape juice, either with single non-Saccharomyces or with mixed S. cerevisiae/non-Saccharomyces inocula. In all mixed cultures, non-Saccharomyces yeasts grew to...
متن کاملSaccharomyces and Non-Saccharomyces Starter Yeasts
This chapter describes the importance of yeast in beer fermentation. Initially, the differences between Saccharomyces cerevisiae and Saccharomyces pastorianus in the production of “ale” and “lager” beers are analyzed. Then, the relationships between beer nutrients and yeast growth are discussed, with special emphasis on the production of the flavor compounds. The impact of the wort composition ...
