Because it was excreted too quickly by the human body, which reduced its ability to kill the bacteria.
The discovery of penicillin is attributed to Scottish scientist and Nobel laureate Alexander Fleming in 1928.He showed that, if Penicillium notatum were grown in the appropriate substrate, it would exude a substance with antibiotic properties, which he dubbed PENICILLIN.
Alexander Fleming found penicillin hard to work with because he struggled to isolate and purify the compound from the mold, which was a time-consuming and challenging process. Additionally, the mold produced penicillin in small quantities, making it difficult to obtain enough for effective use.
Alexander Fleming faced challenges in trying to isolate and purify penicillin, including obtaining enough of the substance in a pure form to be effective as a medicine. He also had to overcome skepticism from the medical community and pharmaceutical industry about the potential of penicillin as a revolutionary antibiotic. Lastly, Fleming had to find a way to mass-produce penicillin in order to make it widely available for treatment of bacterial infections.
Alexander Fleming's goal was to find a cure for bacterial infections. He discovered penicillin in 1928, which revolutionized the field of medicine by introducing the first antibiotic to treat bacterial infections effectively. Fleming's work helped pave the way for the development of other antibiotics and significantly improved healthcare outcomes worldwide.
Sir Alexander Fleming wanted to solve the problem of bacterial infections and find a way to effectively treat them. He discovered penicillin, the first antibiotic, which revolutionized medicine by providing a way to combat bacterial infections that were previously untreatable. Fleming's goal was to find a way to effectively fight off these infections and save lives.
1928
The mold was growing in one of his experimental bacterial cultures and killing them, ruining the experiment. Others might have thrown it out, he determined what the mold was making that killed bacteria.
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.
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.
Well there were two things I found when researching him for a debate. 1. In 1949 his wife died and only four years later he remarried 2. He tested penicillin on animals I hope this helps, and if I find more I will be sure to respond :)
I read in a book called 'Alexander and the Story of Pencillin' that Fleming's son is named Robert, though I have been unable to find any other information on the internet with that name.
This is an urban legend. You will find it listed as such in several of the fact-checking sites, including Snopes.com. You will also find the true story of who paid for Alec Fleming's education (it was an uncle) in the wikipedia article on Alexander Fleming.
