When it first was discovered, it was only recognized as being dangerous to animals. Later in the 80s, due to several outbreaks of bacteria-contaminated food, this bacteria were seen as a threat to public health.


Screening of Spoilage Yeasts in Wine

Screening of Spoilage Yeasts in Wine

Winemaking is a non-sterile process and the role of yeast in fermentation is essential to the production of the fermented alcoholic beverages. Wine fermentation is a complex microbiological process in which specific yeasts strains are selected to obtain the desired fermentation characteristics – flavor and aroma – in the final product. Saccharomyces cerevisiae is the main microorganism involved, due to their fast fermentation rates and ability to survive in the harsh environmental conditions of wine.
