Pullulare

Pullulare is a genus of fungi in the family Saccharomycetaceae. These yeasts are known for their ability to reproduce both sexually and asexually. They are often found in a variety of environments, including soil, plant material, and as commensals on insects. Species within the genus Pullulare are characterized by their pseudohyphal or hyphal growth forms, which can be a distinguishing feature.

The most well-known species is likely Pullulare pullulans, formerly known as Aureobasidium pullulans. This species has a broad host range and can cause superficial infections in humans, particularly in individuals with compromised immune systems. It is also recognized as a plant pathogen, contributing to various diseases in fruits and vegetables. In industrial settings, Pullulare species have been investigated for their potential in bioremediation and the production of enzymes. Their metabolic versatility allows them to degrade certain pollutants. Research continues to explore the diverse ecological roles and biotechnological applications of fungi within the Pullulare genus.
