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 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.
Other named constituents of natural Penicillium, such as penicillin A, were subsequently found not to have antibiotic activity and are not chemically related to antibiotic penicillins. [8] The precise constitution of the penicillin extracted depends on the species of Penicillium mould used and on the nutrient media used to culture the mould. [8]
The original colony of this mould, which proved to be Penicillium notatum, inhibited the growth of staphylococci in its vicinity, and fluid cultures of it contained a substance, since known as "penicillin", which was strongly inhibitory to the growth of various mainly Gram-positive bacteria. It came to be used at St. Mary's Hospital and ...
Penicillium tardochrysogenum is a filamentous species of fungus in the genus Penicillium which produces penicillin, secalonic acids D and secalonic acids F. [1] [2 ...
