Pseudozyma epicola is a yeast belonging to the family Ustilaginaceae, a group of fungi that includes both plant-pathogenic and non-pathogenic species. Pseudozyma epicola is among the non-pathogenic species and is considered an environmental yeast, often isolated from plant surfaces, soils and decomposing organic material. It appears as oval or ellipsoidal cells that reproduce by budding, forming smooth, creamy colonies.

In the food and biotechnology sectors, Pseudozyma epicola is not used as a direct ingredient, but may be employed as a microbial processing aid in experimental fermentations or for enzyme production. Some related species in the genus Pseudozyma are known for their ability to produce natural biosurfactants, such as mannosylerythritol lipids (MEL), compounds valued in food, cosmetic and industrial applications for their emulsifying properties. However, the use of Pseudozyma epicola is less common than that of other species in the genus and is mainly studied in applied microbiology and research contexts.
