GNU Webster's 1913
- n. (Chem.) Any of a variety of substances having a structure containing a beta-lactam ring fused to a thiirane ring, to which a carboxyl group is attached, but most commonly interpreted as benzyl penicillin. They are notable as powerful antibacterial agents of relatively low toxicity which have found extensive use in medicine for treating bacterial infections. They are categorized as one of the classes of beta-lactam antibiotic. They are produced naturally by some fungi and bacteria, and industrial production processes almost invariably start from some form of penicillin nucleus produced by fermentation of microorganisms. The fermentation products are then chemically modified to produce derivatives of enhanced potency, safety, or antibacterial spectrum. The first
penicillin to see extensive use clinically (during World War II) was penicillin G, also called benzypenicillin, and commonly simply “penicillin”.

Examples
“I'd rather be nice and rotten than covered with those whiskers of mold, although the penicillin is a pretty good preservative.”
“The disease, once easily killed with a shot of penicillin, is increasingly becoming drug-resistant.”
“A shot of penicillin is a cheap cure, but many people never experience specific symptoms and the disease remains undiagnosed.”

“Jake Gyllenhaal makes some snow shoes out of the seats of a pair of wooden chairs (still not thinking to burn them in addition to the, you know, books of Knowledge That Is Wrong) and leads an exhibition to get some penicillin from a stray oil tanker that seems to have negotiated the New York City streets and run aground next door to the NYPL without any trace of a crew on board.”
“In a time when annihilation and destruction through the inventions of man have been greater than ever before in history, the introduction of penicillin is a brilliant demonstration that human genius is just as well able to save life and combat disease.”
“The observation made by Professor Alexander Fleming which led to the discovery of penicillin, is now almost classical.”
“On the other hand, experience has confirmed what might have been surmised, namely that penicillin is not effective in cases of, e.g. tuberculosis, typhoid fever, poliomyelitis, and a number of other infectious diseases.”
“The story of penicillin is well-known throughout the world.”
“In this connection advantage was taken of the observation that the free penicillin is an acid which is more easily dissolved in certain organic solvents than in water, while its salts with alkali are more readily dissolved in water.”
“Clutterbuck, Lovell, and Raistrick, endeavoured to obtain penicillin in the pure form, but without success.”
