Rhodotorula

Rhodotorula is a genus of yeast that belongs to the phylum Basidiomycota. These yeasts are known for their distinctive pink to red pigmentation, which is due to the presence of carotenoid pigments. Rhodotorula are ubiquitous in nature, commonly found in soil, water, air, and on surfaces. They are also frequently isolated from dairy products and are considered part of the normal microflora of many animals, including humans, where they can reside on the skin and mucous membranes.

These yeasts are generally considered non-pathogenic, though in immunocompromised individuals, certain species have been reported to cause opportunistic infections. Rhodotorula species are often facultative anaerobes, meaning they can grow in the presence or absence of oxygen. They reproduce asexually, typically through budding. Their metabolic versatility allows them to utilize a wide range of carbon and nitrogen sources.

Research into Rhodotorula has explored their potential for producing valuable compounds such as lipids, carotenoids, and enzymes. Their ability to degrade various substances has also led to investigations into their use in bioremediation. While primarily known for their pigmentation, their ecological roles and biotechnological applications continue to be subjects of scientific interest.
