Louis Pasteur, father of modern microbiology

Louis Pasteur, father of modern microbiology

Louis Pasteur was a well-known French chemist who was born in Dôle on December 27, 1822 and died in Marnes-la-Coquette on September 28, 1895.

Pasteur noted for his important discoveries in the field of natural sciences. In this way, Pasteur was considered the father of modern microbiology, and it was with him who began the so-called "Golden Age of Microbiology".

Thus, he was the father of the technique called pasteurization. In this way, Louis Pasteur discovered through a microscope that fermentation was not a chemical process, but a microbiological one. It involves two different organisms, specifically two types of yeasts, which form the key to the fermentation process. One of these produces alcohol and the other lactic acid.

With this, he developed a new technique with which microorganisms that spoil beer, wine or milk could be eliminated, storing them in sealed vats in which a temperature of 44 degrees Celsius was reached for a short period of time. This process, called pasteurization, ensures the safety of countless foods throughout the world.

Although the theory quite controversial in its time, it has undoubtedly been one of the foundations of modern medicine and clinical microbiology. Thanks to it, important advances such as vaccine development, sterilization and the creation of antibiotics have been achieved as effective systems to cure and prevent the spread of diseases.

Similarly, Louis Pasteur developed other scientific contributions such as optical isomerism, discovering that tartaric acid had two different types of crystals that had specular symmetry or spontaneous generation theory, which showed that every living being comes from another living being before that and which served as the basis for the germ theory of diseases and cell theory.
