Among Louis Pasteur’s discoveries were molecular asymmetry, the fact that molecules can have the same chemical composition with different structures; that fermentation is caused by microorganisms; and that virulence can be increased as well as decreased.
Louis Pasteur. Louis Pasteur ForMemRS (/ ˈluːi pæˈstɜːr /, 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.
During the mid- to late 19th century, Pasteur demonstrated that microorganisms cause disease and discovered how to make vaccines from weakened, or attenuated, microbes. He developed the earliest vaccines against fowl cholera, anthrax, and rabies.
Sep 28, 2022 · He is widely credited for the germ theory of disease and for inventing the process of pasteurization – which is named after him – to preserve foods. Remarkably, he also developed the rabies...
Sep 24, 2024 · Pasteur’s first important discovery in the study of vaccination came in 1879 and concerned a disease called chicken cholera. (Today the bacteria that cause the disease are classified in the genus Pasteurella.)
In 1857 he presented evidence that all fermentation is caused by microorganisms and that specific microorganisms cause specific kinds of fermentation. Pasteurization. Using his work with fermentation, Pasteur was able to devise a process, now known as pasteurization, to kill microbes and preserve certain products.
Louis Pasteur, French chemist who was one of the most important founders of medical microbiology. Pasteur’s contributions to science, technology, and medicine are nearly without precedent. His accomplishments earned him France’s highest decoration, the Legion of Honour. Learn about his life and discoveries.
