Louis Pasteur ForMemRS (/ ˈ l uː i p æ ˈ s t ɜːr /, French: [lwi pastœʁ] ⓘ; 27 December 1822 – 28 September 1895) was a French chemist, pharmacist, and microbiologist renowned for his discoveries of the principles of vaccination, microbial fermentation, and pasteurization, the last of which was named after him.
Major contributions to the science of microbiology (as a discipline in its modern sense) have spanned the time from the mid-17th century month by month to the present day. The following is a list of notable microbiologists who have made significant contributions to the study of microorganisms .
More generally, in the medical literature, the Pasteur effect refers to how the cellular presence of oxygen causes in cells a decrease in the rate of glycolysis and also a suppression of lactate accumulation. The effect occurs in animal tissues, as well as in microorganisms belonging to the fungal kingdom. [2] [3]
One of the chemical processes that Pasteur studied was the fermentation of sugar into lactic acid, as occurs in the souring of milk. In an 1857 experiment, Pasteur was able to isolate microorganisms present in lactic acid ferment after the chemical process had taken place. [9] Pasteur then cultivated the microorganisms in a culture with his ...
His most important contribution, however, was recognising that putrefaction in wounds is caused by germs, in connection to Louis Pasteur's then-novel germ theory of fermentation. [ a ] [ 6 ] Lister's work led to a reduction in post-operative infections and made surgery safer for patients, leading to him being distinguished as the "father of ...
Jean Baptiste Pasteur, the only son of Louis and Marie Pasteur, was a soldier in the Franco-Prussian War. The tone set by this war contributed to the rivalry between Koch and Pasteur. [ 1 ] The "German Problem", as Germany increasingly gained scientific, technological, and industrial dominance, fed tensions among European nations. [ 3 ]
The first culture media was liquid media, designed by Louis Pasteur in 1860. [2] This was used in the laboratory until Robert Koch's development of solid media in 1881. [3] Koch's method of using a flat plate for his solid media was replaced by Julius Richard Petri's round box in 1887. [2]
Louis Pasteur was known as a pioneer of microbiology and "The father of immunology". [50] People from all over the world wanted to get vaccinated for rabies, so in 1880 l’Institut Pasteur was constructed in Paris. [50] Pasteur's health declined and on his last birthday he was widely celebrated by the scientific community.
