Penicillium chrysogenum (formerly known as Penicillium notatum) is a species of fungus in the genus Penicillium. It is common in temperate and subtropical regions and can be found on salted food products, [ 1 ] but it is mostly found in indoor environments, especially in damp or water-damaged buildings. [ 2 ]
Genome organization of Penicillium chrysogenum virus (PcV) [1] Genomes are linear double-stranded RNA which is around 12.5 kbp in length. The genome codes for four proteins. The genome has three double stranded RNA segments. All have extended highly conserved terminal sequences at both ends. [1] [3]

Penicillium growth can still occur indoors even if the relative humidity is low, as long as there is sufficient moisture available on a given surface. A British study determined that Aspergillus- and Penicillium-type spores were the most prevalent in the indoor air of residential properties, and exceeded outdoor levels. [14]

The principal commercial strain of Penicillium chrysogenum (the Peoria strain) produces penicillin G as the principal component when corn steep liquor is used as the culture medium. [8] When phenoxyethanol or phenoxyacetic acid are added to the culture medium, the mould produces penicillin V as the main penicillin instead.
The mould was identified as Penicillium chrysogenum and designated as NRRL 1951 or cantaloupe strain. [106] [116] The spores may have escaped from the NRRL. [117] [a] [b] Between 1941 and 1943, Moyer, Coghill and Raper developed methods for industrialized penicillin production and isolated higher-yielding strains of the Penicillium fungus.
The surface of a Talaromyces (formerly Penicillium) marneffei colony. Image: James Gathany, CDC. Talaromyces marneffei, formerly called Penicillium marneffei, [1] was identified in 1956. [2] The organism is endemic to southeast Asia, where it is an important cause of opportunistic infections in those with HIV/AIDS-related immunodeficiency.
