Penicillium(redirected from Penicillium citrinum)
Also found in: Dictionary, Thesaurus, Encyclopedia.
a genus of imperfect fungi of the form-class Hyphomycetes; many species are commonly found in the human environment. Some are toxic, and others are sources of penicillins.
A genus of fungi (class Ascomycetes, order Aspergillales), some species of which yield various antibiotic substances and biologicals; for example, P. citrinum yields citrinin; Penicillium claviforme, Penicillium expansum, and Penicillium patulum yield patulin; Penicillium chrysogenum yields penicillin; Penicillium griseofulvum yields griseofulvin; Penicillium notatum yields penicillin and notatin; Penicillium cyclopium and Penicillium puberulum yield penicillic acid; Penicillium purpurogenum and Penicillium rubrum yield rubratoxin. Penicillium marneffei is a true pathogen in Southeast Asia in bamboo rats.
n. pl. peni·cilliums or peni·cillia (-sĭl′ē-ə)
Any of various characteristically bluish-green fungi of the genus Penicillium that grow as molds on decaying fruits and ripening cheese and are used in the production of antibiotics such as penicillin and in making cheese.
A genus of fungi, some species of which yield various antibiotic substances and biologicals.
Penicillium(pĕn″ĭ-sĭl′ē-ŭm) [L. penicillum, brush]
A genus of molds belonging to the Ascomycetes (sac fungi). They form the blue molds that grow on fruits, bread, and cheese. A number of species (P. chrysogenum, P. notatum) are the source of penicillin. Occasionally in humans they produce infections of the external ear, skin, or respiratory passageways. They are common allergens. See: illustration
A species that may cause systemic infections, esp. in immunocompromised patients. It is found most often in Southeast Asia, where it frequently infects patients with acquired immunodeficiency syndrome.illustration
PenicilliumOne of a range of common blue-green moulds of the genus Penicillium , that grow on decaying fruits and ripening cheese. Penicillium species such as P. notatum and P. rubrum were originally studied by Fleming in investigating the properties of the antibiotic penicillin. (Alexander Fleming, 1881–1955, Scottish bacteriologist).
Fungal genus; some species yield various antibiotic substances and biologicals.
