Brotzu is recognized as the discoverer of the cephalosporin-based antibiotics, that were first isolated from cultures of Cephalosporium (now known as Acremonium) in 1948. He noticed that these cultures produced substances that were effective against Salmonella typhi, the cause of typhoid fever, which had beta-lactamase. He was awarded the Laurea ad honorem at the University of Oxford in 1971, and was a candidate also for the Nobel Prize. ==Political career==
