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 ...
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.
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 ...
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 a French chemist, supported the idea that fermentation was a biological process. Justus von Liebig, a German chemist, supported the idea that fermentation was a mechanical process. Both chemists had different methods of experimentation, and they focused on different aspects of fermentation because they had different ideas about ...
Nicolas Appert (17 November 1749 – 1 June 1841) was a French confectioner and inventor who, in the early 19th century, invented airtight food preservation.Appert, known as the "father of food science", [1] described his invention as a way "of conserving all kinds of food substances in containers".
This led him to create the wort stabilisation process, which resulted in a clearer and consistent wort. He then separated the fermentation into stages. In the first stage the yeast grew and in the second the fermentation began. The yeast was thus encouraged to either grow or produce alcohol. As a result, Coutts created a continuous flow between ...
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.
