Question

If the fermentation of molasses during the manufacturing of ethyl alcohol is delayed then the conclusion that can drawn is

• A. Molasses is diluted
• B. Molasses is not diluted
• C. More yeast is added
• D. Temperature is maintained around 410 K

Answer 1

The correct option is B Molasses is not diluted

• The sugarcane molasses are generally used as the fermentation medium.
• The yeast cells are grown in this medium to perform anaerobic respiration which produces ethanol and carbon dioxide.
• The molasses which are used is diluted so that the activity of yeast cells is fast and the production of ethanol occurs at a rapid pace.
• If the process is slowed down, then the molasses must not have been diluted before the addition of the fermentation medium in the fermentor.
• Thus, the correct answer is option B.
