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 (/ ˌ p ɛ n ɪ ˈ s ɪ l i əm /) is a genus of ascomycetous fungi that is part of the mycobiome of many species and is of major importance in the natural environment, in food spoilage, and in food and drug production.
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]
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 first β-lactam antibiotic discovered, penicillin, was isolated from a strain of Penicillium rubens (named as Penicillium notatum at the time). [4] [5] Bacteria often develop resistance to β-lactam antibiotics by synthesizing a β-lactamase, an enzyme that attacks the β-lactam ring.
This is a list of Penicillium species. The genus has over 300 species. [1] Species ... Penicillium notatum. Penicillium nalgiovense [2] Penicillium neocrassum [4]
Some allergy clinics will diagnose you as allergic to "Penicillum" without specifying the particular kind of Penicillium. Meanwhile there has apparently been plenty of research showing some of the culinary varieties have no statistically significant link to allergies, or at least, the form it takes in final products like bleu cheese does not.
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.
