ethanol to acetic acid fermentation
What is acetic acid fermented product called?
The acetic acid fermented product can be called a vinegar of plus the name of the used substrate ( 19 ). The substrate used in the processing of vinegar is mostly of plant origin, including fruits ( e.g. grapes, apple, mango, etc. ), cereals, onion and cider, except for honey vinegar and whey vinegar ( 18, 20 ).
How does yeast convert ethanol to acetic acid?
Under anaerobic conditions, yeasts (typically strains of Saccharomyces cerevisiae) convert fermentable sugars to ethanol, whereas in acetic acid fermentation, AAB convert ethanol to acetic acid by the activity of two membrane-bound enzymes located on the outer surface of the cytoplasmic membrane (periplasmic side) ( 3, 18 ).
What is the role of acetic acid bacteria in fermentation?
This work emphasizes the importance and applications of AAB during the fermentation of various foods, their role in the development of new beverages as well as numerous applications of levan and bacterial cellulose. Acetic acid bacteria (AAB) are mesophilic, Gram-negative bacteria that belong to the Acetobacteraceae family.
How does Acetobacter oxidize ethanol?
Acetobacter uses two membrane-bound enzymes (alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH)) to oxidize ethanol to acetic acid during respiration, after which it further oxidizes acetic acid and lactic acid to carbon dioxide and water.
