Penicillin G (benzylpenicillin) was first produced from a penicillium fungus that occurs in nature. The strain of fungus used today for the manufacture of penicillin G was created by genetic engineering to improve the yield in the manufacturing process. None of the other natural penicillins (F, K, N, X, O, U1 or U6) are currently in clinical use.
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.
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 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 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.

This new Glaxo plant opened at Barnard Castle in January 1946 and produced more penicillin over the next nine months than its surface plants had produced in all of 1945. The surface plants were all closed in 1946. [151] Penicillin production in the UK increased from 25 million units per week in March 1943 to 30 billion per week in 1946. [152]
These include, for example, the beta-lactam antibiotics, which include the penicillins (produced by fungi in the genus Penicillium), the cephalosporins, and the carbapenems. Compounds that are still isolated from living organisms are the aminoglycosides , whereas other antibacterials—for example, the sulfonamides , the quinolones , and the ...
Certain fungi are used to make citric acid, a common ingredient of soft drinks and other foods. Vitamins Microorganisms are used to make vitamins, including C, B 2, B 12. Antibiotics With only a few exceptions, microorganisms are used to make antibiotics. Penicillin, Amoxicillin, Tetracycline, and Erythromycin
