Which Organisms are NOT Involved in Food Fermentations

Question

Which organisms are NOT involved in food fermentations?
A) lactic acid bacteria
B) sulfuric acid bacteria
C) acetic acid bacteria
D) propionic acid bacteria

Accepted Answer

Sulfuric acid bacteria are not involved in food fermentations. They are considered to be spoilage bacteria and can cause food to become rancid or develop off-flavors. The other options (lactic acid bacteria, acetic acid bacteria, and propionic acid bacteria) are all involved in different types of food fermentations.
