When and who created penicillin?
It wasn't really an invention; it was more of an accidental discovery. Alexander Fleming is credited with the discovery. On September 28, 1928, he noticed that a Petri dish that was accidentally left open got moldy, and there was an area around the mold where the culture in the dish would not grow. However, others had written about the antibacterial properties of Penicillium before Fleming.
Who discovered penisilin?
Alexander Fleming won the Nobel Prize for his isolation of penicillin. Other scientists who observed penicillin before him include John Tyndall and Joaquim Monteiro Caminhoa.
What Nobel Prize did Sir Alexander Fleming win and when was it awarded?
Sir Alexander Fleming won the Nobel Prize in Physiology or Medicine in 1945 for his discovery of penicillin.
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.
How was pencillium found?
In 1928, bacteriologist Alexander Fleming made a chance discovery from an already discarded, contaminated Petri dish. The mold that had contaminated the experiment turned out to contain a powerful antibiotic, penicillin. However, though Fleming was credited with the discovery, it was over a decade before someone else turned penicillin into the miracle drug for the 20th century. How did this Petri dish almost get cleaned before being noticed? How did the mold get onto the dish? Who transformed penicillin into a useful drug?

Where was the penicillin discovered?
Penicillin was discovered in 1928 by the Scottish scientist Sir Alexander Fleming accidentally when he was conducting experiments in his laboratory. He noticed that microbes in some of his cultures were killed off by the growth of Penicillium mold. He was able to extract the effective substances and "penicillin" became the first dedicated antibiotic drug.
What wonder drug was used for three years by the Army and Navy before becoming available to the general public in 1944?
Penicillin. It was discovered by Alexander Fleming in 1928 but was not widely used until World War II, where it proved to be highly effective in treating bacterial infections and saved countless lives. It was initially reserved for military use before being made available to the general public in 1944.
Why is howard florey important?
Howard Florey is the man responsible for the development of penicillin it was his observation of an observation and some work done by Fleming who bumped int it accidentally that led to penicillin being developed. Without him it would quite likely have been years later before this discovery was made. Fleming who is generally credited with the discovery had given up any plans to do more with the discovery long before Florey got to it.
How long have antibiotics been invented?
The first observations that penicillium mold killed bacteria was in 1874. Sir Alexander Fleming identified penicillin as the chemical produced by penicillium mold that killed bacteria in 1928. He was able to separate small quantities of penicillin. Ernst Chain, Howard Florey and Edward Abraham succeeded in purifying the first penicillin, penicillin G, in 1942 for the Allied military, but it did not become available outside the Allied military before 1945. However the rapid development of antibiotic resistance due to antibiotic misuse has resulted in penicillin and many other antibiotics now being ineffective on most bacteria. There is only one remaining antibiotic (vancomycin) to which no bacteria have developed any resistance!
How many people died before penicillin was invented?
6000 people died from gonerrhea after penicillin and 9000 or more people died before penicillin.
What was life like before penicillin?
before penicillin ............ many people died of infections such as sore throat and diseases
