The contents of the flask thus remain free of microbes, a property showcased by French microbiologist Louis Pasteur in nineteenth century experiments used to support germ theory as the cause of fermentation over spontaneous generation from bad air .

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 experiments. Pasteur's work on fermentation later led to his development of the germ theory of disease, which put the concept of spontaneous generation to rest. [1]
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.

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 ]
Louis Pasteur was a French chemist who discovered chirality while studying crystals. This discovery became the basis for a new form of chemistry called stereochemistry . [ 49 ] [ 50 ] While Pasteur was studying paratartrate crystals in 1857, he discovered that his calcium paratartaric acid solutions were growing fungi.
The technique of serial passage has been around since the 1800s. In particular, Louis Pasteur's work with the rabies vaccine in the late 1800s exemplifies this method. [7] Pasteur created several vaccines over the course of his lifetime. His work prior to rabies involved attenuation of pathogens, but not through serial passage.
Despite his other successes, Louis Pasteur (1822–1895) was unable to find a causative agent for rabies and speculated about a pathogen too small to be detected using a microscope. [1] In 1884, the French microbiologist Charles Chamberland (1851–1931) invented a filter – known today as the Chamberland filter – that had pores smaller than ...
