Acetic acid bacteria are bacteria that derive their energy from the oxidation of ethanol to acetic acid during respiration. They are Gram-negative, aerobic, rod-shaped bacteria.

The most fundamental reactions in chemistry are the redox processes. ... Ethanol, also known as ethyl alcohol or grain alcohol, is a flammable, colorless, mildly toxic chemical compound with a distinctive perfume-like odor, and is the alcohol found in alcoholic beverages. ... Acetic acid, also known as ethanoic acid, is an organic chemical compound best recognized for giving vinegar its sour taste and pungent smell. ... Cellular respiration is a process similar to combustion where there is an uncontrolled release of energy as light and heat. ... Bacteria that are Gram-negative are not stained dark blue or violet by Gram staining, in contrast to Gram-positive bacteria. ... An aerobic organism or aerobe is an organism that has an oxygen based metabolism. ...

The acetic acid bacteria are found in nature where ethanol is being formed as a result of yeast fermentation of sugars and plant carbohydrates. They can be isolated from the nectar of flowers and from damaged fruit. Other good sources are fresh apple cider and unpasteurized beer which has not been filter sterilized. In these liquids the acetic acid bacteria grow as a surface film due to their aerobic nature and active motility. Vinegar is produced when acetic acid bacteria act on alcoholic beverages such as wine. To meet Wikipedias quality standards, this article or section may require cleanup. ...

Lactose is a disaccharide found in milk. ... Nectar of camellia Nectar, in botany, is a sugar-rich liquid produced by the flowers of plants in order to attract pollinating animals. ... Cider in a pint glass Cider, known in the U.S. as hard cider, is an alcoholic drink made from crushed and then fermented apples. ... Pasteurization (or pasteurisation) is the process of heating food for the purpose of killing harmful organisms such as bacteria, viruses, protozoa, molds, and yeasts. ... For other uses, see beer (disambiguation). ... An aerobic organism or aerobe is an organism that has an oxygen based metabolism. ... Vinegar is often infused with spices or herbs—as here, with oregano. ... Bottles of cachaça, a Brazilian alcoholic beverage. ... Wine is an alcoholic beverage produced by the fermentation of the juice of fruits, usually grapes. ...

Some genera, such as Acetobacter, can eventually oxidize acetic acid to carbon dioxide and water using Krebs cycle enzymes. Other genera, such as Gluconobacter, doesn't further oxidize acetic acid, as they do not have a full set of Krebs cycle enzymes. Acetobacter is a genus of acetic acid bacteria characterized by the ability to convert alcohol (ethanol) to acetic acid in the presence of air. ... Carbon dioxide is a chemical compound composed of one carbon and two oxygen atoms. ... Water is a tasteless, odourless substance that is essential to all known forms of life and is known as the universal solvent. ... The citric acid cycle (also known as the tricarboxylic acid cycle, the TCA cycle, or the Krebs cycle) is a series of chemical reactions of central importance in all living cells that utilize oxygen as part of cellular respiration. ...

Some acetic acid bacteria, notably Acetobacter xylinum, are known to synthesize cellulose, something normally only done by plants. Cellulose as polymer of β-D-glucose Cellulose in 3D Cellulose (C6H10O5)n is a long-chain polymeric polysaccharide carbohydrate, of beta-glucose [1][2]. It forms the primary structural component of green plants. ...

As these bacteria produce acid, they are unusually acid tolerant, growing well below pH 5.0, although the pH optimum for growth is 5.4-6.3. For other uses, see Acid (disambiguation). ... . The initial letter is shown capitalized due to technical restrictions. ...
