eli5: how does a mould (penicillium) become an antibiotic?

713 views

I don’t exactly understand the step from the mould to the pill/medicine. I mean, you couldn’t eat the mould and get the same result, or could you?

Long story short, yes, you could – moldy bread has been used to combat disease for millennia.

The distinction is essentially one of refinement/purification and dosage; the antibiotic is «cleaned» from other substances (such as rotten bread) and bits that might not be quite as good for you, and packed into an easier-to-swallow capsule that is less unappealing than old, moldy bread. 🙂
