Question

Bacteria that oxidize ethyl alcohol to acetic acid and cause spoilage in alcoholic beverages belong to the Genus.

• A. Aeromonas
• B. Acetobacter
• C. Arthrobacter
• D. Campylobacter

Hint:

The name {Acetobacter} itself gives a clue. "Aceto" relates to acetic acid, and "bacter" refers to bacteria. This makes it easy to remember their primary function.

Answer 1

The Correct Option is B

Step 1: Analyze the metabolic process described. The question describes the conversion (oxidation) of ethyl alcohol into acetic acid. This is the characteristic process of vinegar production.
Step 2: Identify the bacterial genus responsible for this process. The genus of bacteria well-known for its ability to perform this oxidation is {Acetobacter}. These bacteria are used commercially to produce vinegar and are also responsible for the spoilage of alcoholic beverages like wine and beer by turning them sour (acetic).
