Expert Solution

Step 1

Alcoholic fermentation occurs in the cells when there is an oxygen-deficient condition around the cell.
Under the oxygen-deprived condition, the cell undergoes anaerobic fermentation that forms alcohol (ethanol) as an end product.
The alcohol is toxic to the living cells and exposure to alcohol kills microbes.
