The secret behind mass-producing penicillin? Cantaloupe mold and sour milk! Scientists in the 1940s were desperately searching for ways to scale up penicillin production during WWII when they discovered a super-productive strain on a moldy cantaloupe in Peoria, IL. Meanwhile, the fermentation techniques came from the dairy industry's sour milk processes. So next time you take antibiotics, remember your life was saved by the unholy alliance between forgotten fruit and spoiled dairy. Medical science: where "eww, that's gross" becomes "eureka, that's gold!"
