Penicillium

Penicillium (pronunciation: /ˌpɛnɪˈsɪliəm/) is a genus of fungi that is of major importance in the natural environment, in food spoilage, and in food and drug production.

Etymology

The name Penicillium comes from the Latin word penicillus, which means "painter's brush", and refers to the way the spore-producing structures (conidiophores) resemble a paintbrush.

Description

Penicillium species are present worldwide and play a crucial role in the decomposition of organic materials, such as plant debris. They also contribute to the maturation and flavor of certain cheeses, such as Roquefort and Camembert.

Medical Importance

Some species of Penicillium are of great medical importance. The most notable is P. chrysogenum, which produces penicillin, a compound that is used as an antibiotic to fight a variety of bacterial infections. Other species are involved in the production of other important drugs, including other antibiotics, immunosuppressants, and cholesterol-lowering drugs.
