Louis Pasteur's interest in fermentation began when he noticed some remarkable properties of amyl alcohol—a by-product of lactic acid and alcohol fermentation—during his biochemical studies. In particular, Pasteur noted its ability to “rotate the plane of polarized light ”, and its “unsymmetric arrangement of atoms."
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.
Fermented foods have a religious significance in Judaism and Christianity. The Baltic god Rugutis was worshiped as the agent of fermentation. [37] [38] In alchemy, fermentation ("putrefaction") was symbolized by Capricorn ♑︎. [citation needed] Louis Pasteur in his laboratory
When the O 2 concentration is low, the two pyruvate molecules formed through glycolysis are each fermented into ethanol and carbon dioxide. While only 2 ATP are produced per glucose, this method is utilized under anaerobic conditions because it oxidizes the electron shuttle NADH into NAD + for another round of glycolysis and ethanol fermentation.
Beer fermenting at a brewery. Zymology, also known as zymurgy, [a] is an applied science that studies the biochemical process of fermentation and its practical uses. Common topics include the selection of fermenting yeast and bacteria species and their use in brewing, wine making, fermenting milk, and the making of other fermented foods.
Louis Pasteur and Robert Koch were contemporaries of Cohn, and are often considered to be the fathers of modern microbiology [16] and medical microbiology, respectively. [18] Pasteur is most famous for his series of experiments designed to disprove the then widely held theory of spontaneous generation , thereby solidifying microbiology's ...
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 .

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 ]
