genus of fungi From Wikipedia, the free encyclopedia
Penicillium is a group, or a genus, of ascomycetous fungi commonly isolated from environments like soil, vegetation, and many food products. It is known to have ecological importance as a decomposer of organic material and cause rotting in food crops by mycotoxin production.[1] Other members of this group are known to produce penicillin’s, a molecule of commonly used antibiotics. Antibiotics kills or stops the growth of certain kinds of bacteria inside the body to reduce or stop infection of harmful bacteria. This genus of 354 species is widely impactful with many applications affecting every modern human today e.g., food and drug production.[2]

The mycelium is a highly branched network of multinucleate, usually colourless hyphae. The conidiospores are the main dispersal route of the fungi, and are often green in colour.
Sexual reproduction involves the production of ascospores. The asci contain eight unicellular ascospores each.
Species of Penicillium are ubiquitous soil fungi preferring cool and moderate climates, commonly present wherever organic material is available. Saprophytic species of Penicillium and Aspergillus are among the best-known representatives of the Eurotiales. They live mainly on organic biodegradable substances. Commonly known as moulds, they are among the main causes of food spoilage.[3] Many species produce toxins which work against bacteria and other fungi. The ability of these Penicillium species to grow on seeds and other stored foods depends on their ability to thrive in low humidity and to colonize rapidly by aerial dispersion while the seeds are sufficiently moist.[4] Some species have a blue colour, commonly growing on old bread and giving it a blue fuzzy texture.
