Louis Pasteur made the decisive discovery that a special type of bacteria, later known as acetic acid bacteria, was the agent of fermentation for vinegar production. [10] In the 20th century, vinegar production was again revolutionized by the invention of the submerged fermentation process that cut production times down to 1–2 days. [11]
Mother of vinegar in a bottle. Mother of vinegar is a biofilm composed of a form of cellulose, yeast, and bacteria that sometimes develops on fermenting alcoholic liquids during the process that turns alcohol into acetic acid with the help of oxygen from the air and acetic acid bacteria (AAB).
Acetic acid bacteria (AAB) are a group of Gram-negative bacteria which oxidize sugars or ethanol and produce acetic acid during fermentation. [1] The acetic acid bacteria consist of 10 genera in the family Acetobacteraceae. [1] Several species of acetic acid bacteria are used in industry for production of certain foods and chemicals. [1]
Industrial vinegar-making methods accelerate this process by improving the supply of oxygen to the bacteria. [44] The first batches of vinegar produced by fermentation probably followed errors in the winemaking process. If must is fermented at too high a temperature, acetobacter will overwhelm the yeast naturally occurring on the grapes. As the ...
The production of vinegar, which come from fermented fruits or grains, dates back thousands of years. Ancient civilizations have used vinegar for medicinal and cooking purposes. As time went on, people paid more and more attention to the process of fermentation, which converts sugars into alcohol and then into vinegar in the presence of oxygen.
Tibicos water crystals made with Muscovado. This is a list of fermented foods, which are foods produced or preserved by the action of microorganisms.In this context, fermentation typically refers to the fermentation of sugar to alcohol using yeast, but other fermentation processes involve the use of bacteria such as lactobacillus, including the making of foods such as yogurt and sauerkraut.

The acetic fermentation was demonstrated by Louis Pasteur, who discovered the first acetobacter - Acetobacter aceti - in 1864.. In 1998, two strains of Acetobacter isolated from red wine and cider vinegar were named Acetobacter oboediens and Acetobacter pomorum.
