Geotrichum candidum

Geotrichum candidum is a fungus which is a member of the human microbiome, notably associated with skin, sputum, and faeces where it occurs in 25–30% of specimens. It is common in soil and has been isolated from soil collected around the world, in all continents.

G. candidum is the causative agent of the human disease geotrichosis and the plant disease sour rot which infects citrus fruits, tomatoes, carrots, and other vegetables. It can affect harvested fruit of durians such as Durio graveolens.

G. candidum is used widely in the production of certain dairy products including rind cheeses such as Camembert, Saint-Nectaire, Reblochon, and others. The fungus can also be found in a Nordic yogurt-like product known as viili where it is responsible for the product's velvety texture.

In a 2001 study, G. candidum was found to consume the polycarbonate found in CDs.
