Moulds that are developed on the surface of bloomy rind cheeses (Camembert, Brie) and internally in blue veins (see moulds).
It is commonly found in carpet, wallpaper, and interior fiberglass duct insulation. It may cause hypersensitivity pneumonitis and skin allergy problems. Some species can produce poisons (mycotoxins). It is a common cause of extrinsic asthma. Acute symptoms include edema and bronchiospasms; chronic cases may develop pulmonary emphysema. Penicillium is the second most dangerous mold (agter Stachybotrys) because it attacks lung tissues.
genus of fungi commonly growing as green or blue molds on decaying food; used in making cheese and as a source of penicillin
Molds which are developed either internally in blue-veined cheeses or on the surface of bloomy rind cheeses.
A genus of fungi characterized by their structure and commonly referred to as the penicillins.
Many species are common contaminants on a variety of substrates. May be found indoors in air samples, carpet dust, or on wallpaper. Some species are able to produce mycotoxins, as summarized below. Human pathogenic species are rare, only limited to P. marneffei, which causes disease in immunocompromised individuals. Some species are used for commercial production, such as P. chrysogenum for the antibiotic penicillin, P. griseofulvum for the antibiotic griseofulvin, and P. roquefortii for blue cheese.

sp. Aw: 0.78–0.88 A wide number of organisms have been placed in this genus. Identification to species is difficult. Often found in aerosol samples. Commonly found in soil, food, cellulose and grains. It is also found in paint and compost piles. It may cause hypersensitivity pneumonitis, allergic alveolitis in susceptible individuals. It is reported to be allergenic (skin) . It is commonly found in carpet, wallpaper, and in interior fiberglass duct insulation. Some species can produce mycotoxins. Common cause of extrinsic asthma (immediate-type hypersensitivity: type I). Acute symptoms include edema and bronchiospasms, chronic cases may develop pulmonary emphysema.
(pen-uh-sill'-ee-um) - contaminant / opportunistic pathogen, one of the most common genera found worldwide in soil and decaying vegetation and indoors in dust, food, and various building materials. Common bread mold is a species of Penicillium. Spores usually cannot be distinguished from Aspergillus on non-cultured samples (like tape-lifts and air-o-cells). It is reported to be allergenic, to cause certain infections in compromised individuals, and some species do produce toxins unhealthy to humans.
Principal genus of fungi used to develop molds on certain cheese varieties during ripening. Penicillium candidum is used to develop many soft-ripened cheeses such as Brie; Penicillium glaucum or roqueforti are used for Gorgonzola and Roquefort cheeses, respectively.
