Geotrichum candidum is a fungus or mold that can act as a plant pathogen causing sour rot on peach, nectarine, tomato, carrot and lemon. The fungus can also cause lung disease in humans, called geotrichosis. It is also widely used in the production of many dairy products including many natural rind cheeses such as Camembert and other bloomy rind cheese, Saint-Nectaire, Tomme de Savoie, and many other cheeses made in those styles. It is also found in the Nordic dairy product viili and causes its velvety surface. One of the leading experts in how this mold affects cheeses during aging is Sister Noella Marcellino of the Abbey of Regina Laudis.
The mold can be found in many sources (plant, animal, dairy products, soil). This and other species of Geotrichum can also cause human disease.
In addition to its organic diet, Geotrichum candidum has been observed as eating the polycarbonate and aluminium layers in compact discs.
