Hanseniaspora

Hanseniaspora is a genus of yeast that belongs to the family Saccharomycetaceae. It is commonly found in various environments, including soil, water, and plant surfaces. Hanseniaspora species are known for their ability to ferment sugars and produce ethanol, making them useful in industrial applications such as brewing and winemaking. They are also significant in the context of spoilage and contamination in food and beverage products.

The genus Hanseniaspora was first described by Lodder and Kreger-van Rij in 1958. It is characterized by its ascospores, which are typically ellipsoidal to ovoid in shape. The genus includes several species, with Hanseniaspora uvarum being one of the most well-known. This species is often encountered in wine and beer, where it can contribute to off-flavors and spoilage.

Hanseniaspora species are typically non-pathogenic to humans, but they can cause infections in immunocompromised individuals. They are also known to produce mycotoxins, which can be harmful to both humans and animals. Despite these potential risks, Hanseniaspora species play important roles in various ecological and industrial processes, making them a subject of ongoing research and study.
