The chemist and bacteriologist Louis Pasteur
Introduction
Louis Pasteur was a French chemist and bacteriologist born on September 27, 1822 in Dole France, had various fields and natural sciences especially in chemistry and microbiology. To him is due to the technique known as pasteurization and through experiments refute the theory of spontaneous generation and developed the germinal theory of infectious, is the pioneering disease of modern microbiology or golden age of microbiology, this led toImportant innovations such as vaccines, antibiotics, sterilization and hygiene such as cure and prevention methods against infectious diseases. This idea represents the beginning of scientific medicine by demonstrating that it is a visible effect (signs and symptoms). Is to look for the germ causing each disease to be able to change it.
Developing
Luis Pasteur had its first important contribution in organic chemistry with the discovery of tartaric acid dimorphism by observing the microscope that the rankic acid presented two types of glass, with specular symmetry, contradicting the discoveries of Eilhard Mitscherlich, this was the dextrogyry discovery andLeuigiras that diverted the plane of polarization of light with the same angle but in the opposite direction. Luis Pasteur solved the mystery of tartaric acid CC4H606. This tartaric acid comes from living beings example that of wine.
Pasteur examined the microscope tiny crystals formed from the systemized tartaric acid in the laboratory there were crystals of two different types with specular symmetry, like our hands, the composition was the same, but the way in which the atoms were associated could takeTwo different and symmetrical forms, while one form polarized light on the other the other polarized to the left.
At 26, Pasteur examined crystals formed from natural tartaric acid, they were only of the two types, living beings produced acid in a way that only one of them was created, and the one that polarized the light to the rightHe won legion of honor.
Pasteur in his study of microbiology pasteurization discovered that in reality, two organisms-dot variants intervened that were the key to the process, one produced alcohol and the other, lactic acid, which sour wine. It was a method to eliminate microorganisms capable of degrading wine, beer or milk and was enclosing the liquid into well sealed targe.
Pasteur showed that every process of fermentation and organic decomposition is due to the action of living organisms and that the growth of microorganisms in nutritional broths was not due to spontaneous generation.
Pasteur showed that microorganisms did not form spontaneously inside the broth, thus refuting the theory of spontaneous generation and demonstrating that every living being comes from another previous living being this scientific principle that was the basis of the germinal theory ofdiseases and cell theory and meant a conceptual change about living beings and the beginning of modern microbiology. Announced its results at a bribes gala in 1864 and obtained a triumph.
Pasteur also made the germ theory of infectious diseases after solving the problem of the wine industry, Pasteur was contacted in 1865 by the French government to help solve the cause of a disease of the silkworms of the south of France, thewhich was ruining production. He undertook an rehearsal and error investigation for four years and after meticulously study. Through the microscope he discovered that they really did not have a disease, but two, from two parasites that infected the worms in their initial stage and the leaves of which they fed and said the infected eggs and leaves had to be destroyed and replaced by new new ones. That a rigorous selection was able to isolate a healthy group and took care that it was not infected.
After a local Silk time he collected the fruits of his contribution and obtained profits for the first time in a decade and countries such as Australia and Italy mimicked their selection technique. This increased its form and attracted their attention to the rest of contagious diseases.
conclusion
The idea that diseases can be transmitted among living creatures was evident in epidemics, such as the crazy outbreak of 1854 on Broad Street. Pasteur Develop the germinal theory of infectious diseases, according to which every infectious disease has its cause (etiology) in a living microscope entity with the capacity to spread among people, in addition to being the cause of chemical processes such as decomposition and fermentation ofInside the body due to an imbalance of moods how its theory was traditionally believed it was controversial and unpopular: it was ridiculous to think that something insignificantly small until the invisible could cause the death of much stronger beings. Pasteur himself, in 1871 he suggested to the doctors of military hospitals to boil instruments and veneages. He discovered an oven, called the pasteur oven, useful to sterilize surgical instruments and laboratory material and had whole support in it.
