In 1928, Sir Alexander Fleming was studying Staphylococcus bacteria growing in culture dishes. He noticed that a mold
called Penicillium was also growing in some of the dishes. A clear area existed around the mold because all the bacteria
that had grown in this area had died. In the culture dishes without the mold, no clear areas were present.
Fleming hypothesized that the mold must be producing a chemical that killed the bacteria. He decided to isolate this
substance and test it to see if it would kill bacteria. Fleming transferred the mold to a nutrient broth solution. This solution
contained all the materials the mold needed to grow. After the mold grew, he removed it from the nutrient broth and then
added the broth to a culture of bacteria. He observed that the bacteria in the culture died. Fleming's experiments were
later used to develop antibiotics.

Alexander Fleming (1881-1955) was a Scottish bacteriologist who discovered penicillin, an antibiotic identified by the substance that moved around a fungus of the species Penicillium notatum.

1: State the issue or problem that Fleming investigated.

he investigated the contamination of a fungus that produced antibiotic substances

2 What was Fleming's hypothesis?

That the fungus produced antibiotics and inhibited the growth of bacteria

3 How was the hypothesis tested?

He made a nutritive broth, where he placed the fungus, after growth, he extracts the substances

4 Write a statement that summarizes the results of the experiment.

He discovered that antagonistic microorganisms may have biochemical devices, such as the production of antibiotic substances, in order to survive.

5 The Lear experiment for the development of what major medical breakthrough?

Yes, after this discovery millions of people did not die from bacterial infections.

With this information, we can conclude that Fleming performed several experiments concluding that the fungus Penicillium notatum had a substance capable of killing bacteria. This substance was called penicillin.
