Geotrichum candidum is a ripening agent in the production of certain types cheese. Geotrichum candidum grows rapidly on cheese surfaces and also assists in the development of the cheese when used with Penicillium candidum and brevibacterium linens, which require a neutral environment. Geotrichum candidum produces a thick, velvety surface cover with minimal enzyme activity. Due to its proteolytic and lipolytic activity, Geotrichum candidum plays a significant role in the ripening process and greatly influences cheese appearance, structure and flavor. In some applications, such as goat cheese, Geotrichum candidum is used alone to cover the surface.
