Geotrichum candidum is a filamentous yeast-like fungus. G. candidum strains exhibit wide phenotypic variability, from the yeast-like form to the mould-like one. It is an ubiquitous organism found in various sources, such as air, soil, water, silage, digestive tract and interior organs of different mammalians. It is a component of the natural flora of milk and is used as a maturing agent for both soft and hard cheeses. G. candidum has long been the subject of biochemical and physiological studies due to its biotechnological significance and common occurrence. Genome of G.candidum can be an invaluable source of genes coding for various enzymes that might be useful for biotechnology.
