Lactobacillus) and enzymes to convert sugars, starches and carbohydrates found in the food into alcohol and preserving acids (ie acetic acid). This process is called lactic acid fermentation. Bacteria and yeasts (for example in beer brewing) commonly use fermentation as their energy source. Although acetic acid bacteria (AAB) are commonly found in spontaneous or backslopped fermented foods and beverages, rather limited knowledge about their occurrence and functional role in natural food fermentation ecosystems is available. Vinegar was produced only for local consumption until the middle ages. The acetic acid fermentation by acetic acid producers from the Acetobacter species converts alcohol to acetic acid in the presence of excess oxygen. This is how kimchi and yogurt are made. Introduction. AAB are ubiquitous, aerobic, Gram-negative bacteria belonging to the Acetobacteraceae , and the genera Acetobacter , Gluconobacter , Gluconacetobacter , and Komagataeibacter constitute the common AAB found in food and beverage fermentation such as cocoa, milk kefir, water kefir, kombucha, and acidic … Yet, they are promising starter cultures either to better control known food fermentation processes or to produce novel fermented foods and beverages. In second step, acetobacter aceti (acetic acid bacteria) converts ethanol into acetic acid and water. The biologic method accounts for only 10% of world production, but is important for the manufacture of vinegar because many food purity laws require vinegar used in food to be of biological origin.
