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]
“White vinegar is about 5% acetic acid while cleaning vinegar is 6% acetic acid,” she explains. ... and versatile cleaning agent alternative to many toxic household cleaners that can be used ...
The “mother of vinegar”—a mixture of active acetic acid bacteria, yeast, and enzymes created during fermentation—gives this type of ACV a pleasantly funky, more complex flavor profile that ...
Acetic acid / ə ˈ s iː t ɪ k /, systematically named ethanoic acid / ˌ ɛ θ ə ˈ n oʊ ɪ k /, is an acidic, colourless liquid and organic compound with the chemical formula CH 3 COOH (also written as CH 3 CO 2 H, C 2 H 4 O 2, or HC 2 H 3 O 2). Vinegar is at least 4% acetic acid by volume, making acetic acid the main component of vinegar ...
Apple cider vinegar, or cider vinegar, is a vinegar made from cider, [3] and used in salad dressings, marinades, vinaigrettes, food preservatives, and chutneys.

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).
Reducing agents can be ranked by increasing strength by ranking their reduction potentials. Reducers donate electrons to (that is, "reduce") oxidizing agents, which are said to "be reduced by" the reducer. The reducing agent is stronger when it has a more negative reduction potential and weaker when it has a more positive reduction potential.
