Question

Which of the following is maintained for optimum production of vinegar?

• A. Anaerobic condition
• B. Temperature of ${65}^0$C
• C. Aerobic condition
• D. Microaerophilic condition

Answer 1

Answer: (A)

Anaerobic condition

Vinegar is a liquid consisting mainly of acetic acid and water. The acetic acid is produced by the fermentation of ethanol by acetic acid bacteria. Fermentation bacteria are anaerobic and use organic molecules as their final electron acceptor to produce fermentation end products. Acetobacter and Gluconobacter are used in the production of acetic acid or vinegar.
So, the correct answer is 'Anaerobic condition'
