Sir Alexander Fleming, in September 1928, to be exact.
The first antibiotic, penicillin, was made because of the properties found in mold. Alexander Fleming discovered penicillin in 1928 and the drug was found to greatly improve the quality of life in people at that time.
Alexander Fleming was trying to understand why certain strains of bacteria were not growing in his laboratory cultures. He accidentally discovered penicillin when he observed that a mold called Penicillium notatum inhibited the growth of these bacteria. This led to the development of the first antibiotic.
Louis Pasteur was the scientist who noticed that there were no germs around some mold. He discovered that certain molds, like Penicillium, produced a substance that inhibited the growth of bacteria, leading to the development of antibiotic drugs like penicillin.
Alexander Fleming's greatest discovery was penicillin, the world's first antibiotic. In 1928, Fleming accidentally discovered that a mold called Penicillium notatum had antibacterial properties that could kill certain types of bacteria. This discovery revolutionized medicine by providing an effective treatment for 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.
Penicillin is produced by certain types of fungi, specifically Penicillium molds. These molds can be found in the environment, such as in soil or decaying organic matter. Penicillin was first discovered by Alexander Fleming in 1928 when he observed its antibiotic properties.
Alexander Fleming hypothesized that the yellow-green mold, known as Penicillium notatum, released a substance that inhibited the growth of certain bacteria, such as Staphylococcus aureus. This substance was later identified as penicillin, the first antibiotic discovered. Fleming's work laid the foundation for the development of modern antibacterial drugs.
Penicillin is the first antibiotic to be used in practice in 1939. Sulphonamide is 'not' the antibiotic. It is chemical produced in laboratory. Also called as antibacterial chemotherapeutic agent.
The Alexander Fleming, while looking for an antibiotic, failed to clean some of his glassware adequately. It went down in history as one of those "happy accidents" when he noticed something on a not-so-clean petri dish had the properties he was searching for. Namely, suppression of the growth of certain kinds of bacteria.
Fleming discovered that penicillin was a mould that could kill certain types of bacteria that caused disease. The Use of penicillin did not begin until the 1940s when Howard Florey and Ernst Chain made a powder form of penicillin
I'm not sure that Fleming *invented* anything - he's known for *discovering* the antibiotic penicillin by observing that the Penicillium mold secretes a substance that kills certain kinds of bacteria.
