This new mold species produced around 200 times as much penicillin as Fleming's original discovery, Penicillin notatum. By mutating the species using x-rays, Florey and the U.S. team …

The development of antibiotic resistance is a perpetual arms race: as antibiotics are deployed to treat bacterial infections, these bacteria evolve, adopting new mechanisms (such as beta-lactamases) to fight back.

This new mold species produced around 200 times as much penicillin as Fleming's original discovery, Penicillin notatum. By mutating the species using x-rays, Florey and the U.S. team eventually were able to create a strain of the mold which produced 1,000 times more penicillin as Fleming's species.

An accidental discovery in 1928 kickstarted a 20-year long journey to develop the world's first mass produced drug that could clear a bacterial infection; penicillin. But why did it take so long?

Penicillin production mainly consists of three steps: Inoculum: Penicillium chrysogenum. For inoculum production, spores from heavily sporulated working stocks (special agar sporulation) are suspended in water or in a dilute solution of a nontoxic wetting agent, such as 1:10,000 sodium lauryl sulfonate.

Penicillin G (benzy1-penicillin) and penicillin V are the most important naturally occurring penicillins (phenoxymethy1-penicillin). The addition of phenylacetic acid derivatives can induce the synthesis of a desired penicillin.

Penicillin biosynthesis is described into three main steps; catalytic step, oxidative, and exchange of different chains. The catalytic step involves an ACV synthetase enzyme that condenses the lateral chain of cysteine, valine, and alpha aminoadipate into tripeptide ACV.

Florey and Chain developed a system of growing penicillin: which was complicated initially, and tested its effectiveness on mice. The tests were successful and the two men became convinced that the drug would cure many people who would otherwise die.
