The sentence given is missing a subject, and as such, it is not a complete sentence. The correct sentence should be "The fact that penicillin kills bacteria was discovered in 1928 by Alexander Fleming."
Explanation:
The discovery of penicillin by Alexander Fleming in 1928 was a significant breakthrough in the field of medicine. Penicillin is a group of antibiotics that are used to treat bacterial infections by inhibiting the growth of bacteria or killing them outright. Before the discovery of penicillin, bacterial infections were a significant cause of morbidity and mortality.
Alexander Fleming discovered penicillin by chance, while he was conducting research on Staphylococcus bacteria. He noticed that a mold had contaminated his Petri dishes and that the bacteria surrounding the mold had stopped growing. This led him to investigate further and isolate the substance responsible, which he named penicillin.
The discovery of penicillin revolutionized medicine and led to the development of many other antibiotics. Today, antibiotics are widely used to treat bacterial infections and have saved countless lives. However, their overuse has also led to the emergence of antibiotic-resistant bacteria, which is a growing concern in the medical community.
