    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.

  3. Fermentation - Wikipedia

    en.wikipedia.org/wiki/Fermentation

    Fermentation is a type of redox metabolism carried out in the absence of oxygen. [1] [2] During fermentation, organic molecules (e.g., glucose) are catabolized and donate electrons to other organic molecules. In the process, ATP and organic end products (e.g., lactate) are formed. Because oxygen is not required, it is an alternative to aerobic ...

  4. Fermentation theory - Wikipedia

    en.wikipedia.org/wiki/Fermentation_theory

    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 ...

  5. History of alcoholic drinks - Wikipedia

    en.wikipedia.org/wiki/History_of_alcoholic_drinks

    Although the oldest recorded sparkling wine is Blanquette de Limoux, in 1531, [59] the English scientist and physician Christopher Merret documented the addition of sugar to a finished wine to create a second fermentation six years before Dom Perignon joined the Abbey of Hautvillers and almost 40 years before it was claimed that he invented ...

  6. Fermentation in food processing - Wikipedia

    en.wikipedia.org/wiki/Fermentation_in_food...

    Grapes being trodden to extract the juice and made into wine in storage jars. Tomb of Nakht, 18th dynasty, Thebes, Ancient Egypt. Sourdough starter. In food processing, fermentation is the conversion of carbohydrates to alcohol or organic acids using microorganisms—yeasts or bacteria—without an oxidizing agent being used in the reaction.

  7. Zymology - Wikipedia

    en.wikipedia.org/wiki/Zymology

    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.

  8. Acetone–butanol–ethanol fermentation - Wikipedia

    en.wikipedia.org/wiki/Acetone–butanol–ethanol...

    The process may be likened to how yeast ferments sugars to produce ethanol for wine, beer, or fuel, but the organisms that carry out the ABE fermentation are strictly anaerobic (obligate anaerobes). The ABE fermentation produces solvents in a ratio of 3 parts acetone, 6 parts butanol to 1 part ethanol.

    Thomas Bramwell Welch (December 31, 1825 – December 29, 1903) was a British–American Methodist minister and dentist.He pioneered the use of pasteurization as a means of preventing the fermentation of grape juice.
