Question

_______is used in production of vinegar from alcohol.

Answer 1

Hint: Acetobacter is used in production of vinegar from alcohol. During fermentation these bacteria oxidise ethanol to make vinegar and these bacteria are gram-negative bacteria.

Complete answer:
Acetobacter is an aerobic nitrogen-fixing bacteria that is produced for acid as a result of metabolic processes. All nitrogen-fixing bacteria contain nitrogenase enzyme; it is utilizing atmospheric nitrogen gas as a source for metabolic biosynthesis; different nitrogen-fixing microorganisms protect the oxygen-sensitive microorganisms from oxygen exposure in different ways.
A good example of A. diazotrophicus is interesting because it carries out nitrogen fixation under aerobic conditions. for the production of large quantities of ATP required oxygen for nitrogen fixation
A. diazotrophicus is a plant endophyte and it is capable of secreting about half of its fixed nitrogen in a form that plants can use. Production of Vinegar is made from the conversion of ethyl alcohol to acetic acid by a genus of bacteria, Acetobacter. Therefore, vinegar can be produced from any alcoholic material from alcohol-water mixtures to various fruit wines Vinegar bacteria, also called acetic acid bacteria and are members of the genus Acetobacter. Vinegar is a solution of acetic acid produced by a two-step.
In the fermentation step fermentable sugars are transformed into ethanol by the action of yeast. In the second step, acetic acid bacteria oxidize the ethanol into acetic acid in an aerobic process. The key role of vinegar production, raw material preparation and the alcohol fermentation. Microbial species involved in fermentations may range from yeast and lactic acid bacteria to molds and acetic acid bacteria.

Additional information:
This is a slow process to produce vinegar and not very efficient. It appears that there is a loss of alcohol and acetic acid under this process possibly because the surface area was so large. The bacteria in the generator were slow growing even when the generator unit was operating under perfect conditions.

Note: A Gram staining prefer on a representative sample of vinegar from commercial
submerged and generator processes indicated predominantly gram-negative bacteria.
