Alexander Fleming discovered penicillin on September 28, 1928. He noticed that a mold called Penicillium notatum had contaminated one of his bacterial cultures and was inhibiting the growth of bacteria. This serendipitous observation led to the development of penicillin, the world's first antibiotic, which has had a profound impact on medicine. Fleming's discovery marked the beginning of a new era in the treatment of bacterial infections.

Mold has been around for millions of years and likely was first discovered by early humans as a common presence on food that had spoiled. The first recorded observations of mold date back to ancient Egypt and Greece, where it was noted that certain types of mold could be harmful or beneficial to human health.

its wrong answer how could a scientist be born in 200611 june he could be now alive and he id died
All penicillin will go bad after a period of time, but it is actually better to keep liquid penicillin refrigerated. It is a good idea to check the expiration date on your penicillin, and dispose of it when it expires. Penicillin that has gone bad will not help you, and you should be careful with medications that are past their date.
All medications have an expiration date. Penicillin prescribed should have a dispose of date on the label. It is best to consult a doctor for a new prescription, and discard old medication.
This will depend upon how "out of date" the penicillin is, how it has been stored and if the seal on the bottle has been breached. Penicillin is a fairly cheap drug, so when in doubt I suggest simply purchasing a new bottle if needed.
hell yeah she should
