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.
In biochemistry, fermentation theory refers to the historical study of models of natural fermentation processes, especially alcoholic and lactic acid fermentation. Notable contributors to the theory include Justus Von Liebig and Louis Pasteur , the latter of whom developed a purely microbial basis for the fermentation process based on his ...
In 1865 Lister read French chemist's Louis Pasteur's work on the fermentation and distilling process at a winery in France. The wine was contaminated and Pasteur used heat to destroy the responsible bacteria. [45] Pasteur also noted if there was an absence of air, the fermentation of wine was impossible.

The second half of the 20th century was the golden age of virus discovery and most of the 2,000 recognised species of animal, plant, and bacterial viruses were discovered during these years. [ 58 ] [ 59 ] In 1946, bovine virus diarrhea was discovered, [ 60 ] which is still possibly the most common pathogen of cattle throughout the world [ 61 ...
The turning point came when Louis Pasteur (1822–1895), during the 1850s and 1860s, repeated Schwann's experiments and showed fermentation is initiated by living organisms in a series of investigations. [20] [40]: 6 In 1857, Pasteur showed lactic acid fermentation is caused by living organisms. [42]
