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 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 ...
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] Fleming's original strain of Penicillium rubens produces principally penicillin F, named after Fleming. But penicillin F is unstable, difficult to isolate, and produced by the mould in ...
A medallion containing some of the original mold involved in the discovery of penicillin is expected to fetch up to $50,000 at auction.
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.

Penicillium camemberti and Penicillium roqueforti are the molds on Camembert, Brie, Roquefort, and many other cheeses. Penicillium nalgiovense is used in soft mold-ripened cheeses, such as Nalžovy (ellischau) cheese, and to improve the taste of sausages and hams, and to prevent colonization by other molds and bacteria.

The life-saving antibiotic penicillin is made from Penicillium mold, Dr. Ivanina notes. This is why the mold that pops up on your breakfast muffin may look different than the furry layer that ...
Fleming was the first to discover the properties of the active substance, giving him the privilege of naming it: penicillin. He also kept, grew, and distributed the original mould for twelve years, and continued until 1940 to try to get help from any chemist who had enough skill to make penicillin.
