Penicillium roqueforti is a filamentous fungus used for making blue cheeses worldwide. It also occurs as a food spoiler and in silage and wood.
It is used as a fungal starter culture for the production of several blue-veined kinds of cheese, with both proteolytic and lipolytic enzymes produced by the fungus involved in cheese ripening and flavor production. The fungus has the lowest oxygen requirements for the growth of any Penicillium species.
