Geotrichum vs. Geotrichum candidum



Geotrichum is a genus of fungi found worldwide in soil, water, air, and sewage, as well as in plants, cereals, and dairy products; it is also commonly found in normal human flora and is isolated from sputum and feces. It was first described in 1809 by Johann Heinrich Friedrich Link.
The genus Geotrichum includes several species: The most common species is Geotrichum candidum. Geotrichum clavatum and Geotrichum fici are among other Geotrichum species. Geotrichum fici has an intense smell resembling that of pineapple.
Geotrichum candidum is a fungus or mold that can act as a plant pathogen causing sour rot on peach, nectarine, tomato and carrot. 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 is responsible for the velvety surface of the product. One of the leading experts in how this mold affects cheeses during aging is Sister Noella Marcellino of the Abbey of Regina Laudis.
