What qualities can we learn from Alexander Fleming?
From Alexander Fleming, we can learn qualities such as curiosity, perseverance, and the importance of making observations. His discovery of penicillin was a result of his keen interest in understanding bacteria, his dedication to investigating unusual occurrences, and his willingness to pursue unexpected findings.
What did sir Alexander Fleming discover?
In 1928, Fleming was working on the staphylococcibacteria - the kind that cause boils and sore throats, when, whilst he was examining some old bacterial plates that he noticed a mould had grown on one of his cultures. He saw what he believed was unusual in that some of the colonies of staphylococci that should have been growing near the mould had disappeared. Fleming thought that the mould could be making something that was capable of destroying the bacteria. He did some more experiments and found that this was indeed the case. He cultured the mould by growing it in broth. The mould was later identified as Penicillium notatum which had produced what we now call penicillin.
Explain the effect of penicillin on prokaryotic and eukaryotic cells?
Penicillin inhibits the synthesis of bacterial cell walls by targeting the enzymes involved in their production, which are specific to prokaryotic cells. In contrast, eukaryotic cells have different cell wall structures and are not affected by penicillin. This makes penicillin selectively toxic to bacteria, making it an effective antibiotic while sparing eukaryotic cells.
Who discover biomes?
The concept of biomes was popularized by German scientist Friedrich Ratzel in the late 19th century. However, the idea that distinct regions have unique collections of plants and animals predates Ratzel, with early naturalists like Alexander von Humboldt making observations on biogeography.
Is penicillin gram negative or gram positive?

Alexander Fleming discovered penicillin by making the study of what?
Alexander Fleming discovered penicillin by studying mold. He noticed that the mold Penicillium notatum had antibacterial properties that could be used to fight infections. This discovery revolutionized medicine and led to the development of the first antibiotic.
How did Alexander Fleming's invention work?
Alexander Fleming discovered penicillin, the world's first antibiotic, by observing that a mold called Penicillium notatum inhibited the growth of bacteria. The penicillin produced by the mold effectively killed or slowed the growth of many types of harmful bacteria, making it a groundbreaking treatment for bacterial infections. Fleming's discovery revolutionized medicine and has saved countless lives since its development.
Why did Alexander Fleming find penicillin hard to work with?
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.
Why was Alexander Fleming so important?
Alexander Fleming was a doctor and bacteriologist who discovered penicillin, receiving the Nobel Prize in 1945.Penicillin was the first antibiotic we ever had. His discovery was accidental but he was able to see the process behind it. He noticed that, on a plate used in Microbiology labs, that there was mold that wasn't supposed to be there. He also noticed that there was space around the mold and the bacteria growing there. The mold was making something that prevented the bacteria from growing any closer.When he studied that clear area, a product made by the mold was what prevented the bacteria from growing. The mold was Penicillin notatum. The product was called penicillin.
Which microbe is peneillin?
Penicillin is not a microbe itself; it is an antibiotic derived from the mold Penicillium chrysogenum. Discovered by Alexander Fleming in 1928, penicillin works by inhibiting bacterial cell wall synthesis, making it effective against various bacterial infections. The mold produces the antibiotic as a defense mechanism against bacteria.

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.
How did science and technology develop penicillin?
because of Alexander Fleming making a chance discovery Florey and chain were able to make more developments on this new antibacterial fungus-which is what penicillin actualy is-21 years later with more updated science and technology to define it into a brown powder which could be consumed by humans.
Does Alexander Fleming deserve the Nobel Prize?
Alexander Fleming got out of making penicillin a medicine to curing a diseases that can have symptoms of mucus and saliva that may have gotten you sick. And the medicine "Penicillin" could cure it but the ? and it helps you get better.He also received many grants from different organizations and some he kept for himself. He also got to travel around the world showing his invention but American inventors got patents for what he didFleming discovered Penicillin by accidentally leaving a dish of Staphylococcus bacteria out uncovered. After a few days, he saw that there was one area of the dish where mold was growing.
What were Alexander Flemings's talents?
Alexander Fleming was a talented microbiologist known for his discovery of penicillin, the world's first antibiotic. He was also skilled in conducting experiments and making observations that led to significant scientific advancements in the field of microbiology. Fleming's talent for research and innovation paved the way for the development of modern antibiotics.
Who was credited for making penicillin?
Alexander Fleming. In fact, he founded this fungi completely by mistake and his own scientific control error. Sometimes small mistakes have enormous positive results! Change the world!
How did Alexander Flemming find penicillin?
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.
