What difficulty did Alexander Fleming which caused him to stop working on penicillin?
Fleming had found penicillin in bread mold in the year 1928. He squeezed the mold 'juice' out of the bread mold, but it spoiled, even in the refrigerator before he could do anything with it. He was unable to prove that penicillin was an antibiotic, and finally gave up in the year 1934. Others later figured out how to isolate penicillin and make it into a medical form.

When did sir Alexander Fleming invent penicillan?
Alexander Fleming began working with penicillin in 1928 but the work was expanded and finished by other scientist Check Here http://edhelper.com/ReadingComprehension_33_70.html
How do other historians feel about Alexander Fleming?
Fleming admitted to discovering penicillin ''by accident''. That may be somewhat true, but the harder one works at research, the more so-called ''accidents'' do happen. Sir Alexander Fleming was a hard working and brilliant investigator, and this was certainly demonstrated when he became a Nobel Laureate.
When did Alexander Fleming start working and how old was he?
Alexander Fleming started working as a bacteriologist at St. Mary's Hospital in London in 1906 when he was 26 years old.
What could be treated as a result of Alexander Fleming's discover of penicillin?
Alexander Fleming's discovery of penicillin came about by accident. Fleming was an untidy worker, often leaving his equipment uncleaned. When he went away for a holiday during 1828, he left a clutter of plates growing various bacteria lying about his desk. After he returned, whilst working on an influenza virus he noticed that mould had grown on a staphylococcus culture plate. Not only that, the mould had created a bacteria-free circle around itself. Working on an hypothesis, he experimented further to determine that even a weaker-strength mould culture prevented growth of staphylococci. Thus, Fleming initiated the development and practice of antibiotic therapy for infectious diseases.
When was penicillin developed?
Penicillin was first discovered in 1928, by Scottish scientist Sir Alexander Fleming.It was a mistake. He left a petri dish with staphylococcus was left open and found with green - blue mould in it.Alexander Fleming discovered penicillin in 1928 by compete accident. The discovery was made after leaving his desk untidy whilst on holiday. He was working with another substance in staphylococci and left this to go mouldy, it was only later he discovered it had bacteria fighting agents and could be sued as an anti body.Penicillin was discovered in 1928 by a Scottish scientist.
Where and When Were antibiotics first discovered?
Actually it was Sir Alexander Fleming who invented the first antibiotic in 1928, called penicillin. It was considered unsafe and illegal due to lack of testing, so FDA didn't approve it. But the first safe antibiotic was invented in 1945 by British scientist Howard florey(1898-1968) and Ernst Boris Chain (1906-1979) who had expanded the penicillin research of Scottish.
Who is credited with with inventing penicillin?
Originally Englishman Alexander Fleming noticed the activity of penicillin when it had accidentally contaminated a culture he was working on. He made a note of it and did no further work with it. Howard florey an Australian and Ernst Chain got wind of Flemings discovery and went to work to isolate penicillin. They succeeded in producing the drug. however it took the backing and infrastructure of the US department of defense to bring the final development of penicillin to fruition. Once all of the work was completed Fleming stepped in to share in the credit for the discovery.In 1928, Sir Alexander Fleming observed that colonies of the bacterium Staphylococcus aureus could be destroyed by the mold Penicillium notatum, proving that there was an antibacterial agent there in principle. This principle later lead to medicines that could kill certain types of disease-causing bacteria inside the body. At the time, however, the importance of Alexander Fleming's discovery was not known. Use of penicillin did not begin until the 1940s when Howard Florey and Ernst Chain isolated the active ingredient and developed a powdery form of the medicine.Penicillin wasn't invented. It was discovered by accident by Sir Alexander Fleming in 1928 that penicillin killed bacteria. It was discovered at St Mary's Hospital, England.Wikipedia lists Sir Alexander Fleming discovering Penicillin. It was further developed by Howard Walter Florey.Alexander Fleming.Alexander Fleming.

Who is credited with the invention of penicillin?
Discovery of penicillin was one of the most dramatic events in the history of Pharmacology. Sir Alexander Flaming was working in his laboratory in 1928. A stale piece of bread was there in his lab. He observed that there were colonies of bacteria on the same. He observed that around the colonies of some fungi, there was the clear zones. He concluded that the fungi are producing some substance, which is inhibiting the growth of the bacteria. There were lot of casualties during the second world war. There was desperate need to find the drug to treat the infected wounds. Dr. Florry and Chain decided to treat a critical patient with penicillin. They did not know the dose. A round figure was selected. 5000 I U. Now you know that this is very less dose. Thanks God for it worked! The patient stared to recover. But died, when the stock of penicillin was exhausted. The young doctor used to go to hospital, in London, on his bicycle to bring the urine of the patient to recollect the penicillin. I have been wondering from last four decades about how he collected penicillin from the urine! The ultimate result was invention of the ultimate antibiotic, penicillin.
How did Alexander Fleming become interested in science?
Alexander Fleming became interested in science after seeing the medical difficulties and suffering caused by infections during his time working as a doctor in World War I. This experience motivated him to pursue research in bacteriology and find ways to combat harmful bacteria. Fleming's observations and experiments ultimately led to the discovery of penicillin, the first antibiotic, which revolutionized medicine.
What did Alexander Fleming start doing when he moved to London?
When Alexander Fleming moved to London, he began working at St. Mary's Hospital Medical School as a researcher and lecturer. There, he conducted important studies on bacteriology and began his groundbreaking work on antibiotics, ultimately leading to the discovery of penicillin in 1928. His research focused on the properties of bacteria and the potential use of substances to combat infections. This work would later revolutionize medicine and save countless lives.
Who discovered peniciliin?
Alexander FlemingAlexander Fleming (1881-1955) discovered(not invented) the antibiotic effects of the mold in 1928. He was able to extract the chemicals the mold creates that attacks bacteria.
What part did Alexander Fleming play in the history of science?
Alexander Fleming was a scientist, and crucial to the development of penicillin as an important bacteria-fighting agent. Fleming is known for his discovery of the antibiotic substance penicillin from the fungus Penicillium notatum in 1928, for which he shared the Nobel Prize in Physiology or Medicine in 1945. What is more remarkable was how this discovery came about quite by accident. Fleming was an untidy worker, often leaving his equipment uncleaned. When he went away for a holiday during 1828, he left a clutter of plates growing various bacteria lying about his desk. After he returned, whilst working on an influenza virus he noticed that mould had grown on a staphylococcus culture plate. Not only that, the mould had created a bacteria-free circle around itself.
