Zygosaccharomyces is a genus of yeast commonly found in various environments, including soil and decaying plant material. It is particularly known for its role in the fermentation process, especially in the production of certain foods and beverages, such as beer and wine. This yeast can tolerate high sugar concentrations and is often used in the food industry for its unique fermentation properties. One notable species within this genus is Zygosaccharomyces bailii, which is recognized for its ability to survive in acidic conditions and high sugar levels. This resilience makes it a concern in food preservation, as it can spoil products like fruit juices and soft drinks. Understanding Zygosaccharomyces is important for both food production and safety.
