What scientist discovered penicillin in 1928?
Alexander Fleming discovered penicillin in 1928. He observed that a mold called Penicillium notatum had antibacterial properties when it accidentally contaminated his petri dishes while studying Staphylococcus bacteria. This discovery revolutionized medicine and led to the development of the first antibiotic.
What experiments lead to the discovery of penicillin?
Alexander Fleming who discovered penicillin. He was by accident kept a Staphylococcus bacterial plate open which was contaminated by a fungus. What he later noticed strikingly was an area of inhibition of the grown bacteria due to this fungus contamination! Fleming later concluded a chemical released from the fungus inhibited bacterial growth, by this he discovered penicillin!
What kind of data did Alexander Fleming collect?
Alexander Fleming collected data related to the antibacterial effects of Penicillium mold, particularly on Staphylococcus bacteria. He observed that the mold killed the bacteria, leading to the discovery of penicillin.
Why was Fleming's discovery considered accidental?
Fleming's discovery of penicillin was considered accidental because it occurred when he noticed mold growing on a petri dish of Staphylococcus bacteria in his lab. Instead of discarding the contaminated culture, he observed that the bacteria surrounding the mold were being destroyed, leading him to investigate further. This unexpected observation ultimately led to the development of penicillin, marking a significant breakthrough in antibiotic treatment.
Who discovered the penicillin?
Discovery of Penicillin is attributed to Alexander Fleming, a Scottish scientist.
What are antibiotics and how were they first discovered?
Antibiotics are an amalgam of substances derived from microorganisms to control the growth of or kill off bacteria. Most credit Alexander Fleming for the discovery of penicillin and its many uses. Joseph Lister is also considered one of the forerunners in this field.Fleming discovered lysozyme (an antiseptic enzyme that occurs in tissue and secretions such as mucus and tears) in 1921 during his military career. In 1927, he discovered penicillin. The next year while experimenting with the influenza virus he found that a certain strand of penicillin, Penicillium notatum, completely destroyed staphylococcus bacteria in a culture plate. The mold created a "germ-free barrier," if you will, that prevented the staphylococcus from growing. Fleming found that this discovery was effective even when diluted to 800 times.And that's how penicillin was "born."
