Saprophytic species of Penicillium and Aspergillus are among the best-known representatives of the Eurotiales and live mainly on organic biodegradable substances. Commonly known in America as molds, they are among the main causes of food spoilage, especially species of subgenus Penicillium. [9] Many species produce highly toxic mycotoxins.
Like most natural products, penicillin is present in Penicillium moulds as a mixture of active constituents (gentamicin is another example of a natural product that is an ill-defined mixture of active components). [8] The principal active components of Penicillium are listed in the following table: [13] [14]
Production of antibiotics is a naturally occurring event, that thanks to advances in science can now be replicated and improved upon in laboratory settings. Due to the discovery of penicillin by Alexander Fleming, and the efforts of Florey and Chain in 1938, large-scale, pharmaceutical production of antibiotics has been made possible.
Penicillium commune is an indoor fungus belonging to the genus Penicillium. It is known as one of the most common fungi spoilage moulds on cheese. It also grows on and spoils other foods such as meat products and fat-containing products like nuts and margarine.
Penicillium rubens is a species of fungus in the genus Penicillium and was the first species known to produce the antibiotic penicillin. It was first described by Philibert Melchior Joseph Ehi Biourge in 1923. For the discovery of penicillin from this species Alexander Fleming shared the Nobel Prize in Physiology or Medicine in 1945.

The mold Penicillium is used to produce the antibiotic penicillin. Almost half of all members of the phylum Ascomycota form symbiotic associations with algae to form lichens. Others, such as morels (a highly prized edible fungi), form important mycorrhizal relationships with plants, thereby providing enhanced water and nutrient uptake and, in ...
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 ]
Penicillium digitatum (/ ˌ p ɛ n ɪ ˈ s ɪ l i əm ˌ d ɪ dʒ ɪ ˈ t eɪ t əm /) is a mesophilic fungus found in the soil of citrus-producing areas. [ 1 ] [ 2 ] [ 3 ] It is a major source of post-harvest decay in fruits and is responsible for the widespread post-harvest disease in Citrus fruit known as green rot or green mould.
