Acteria, like the Lactobacillus acidophilus use sugar as an energy source for anaerobic cellular respiration. This process produ
ces much less ATP than aerobic respiration and does not produce carbon dioxide as a by-product. It does, however, give yogurt its sour taste and prevents other food spoiling bacteria from developing.This is a description of
Lactic acid fermentation refers to a metabolic procedure by which glucose and other six-carbon sugars, like lactose or sucrose are transformed into cellular energy and the metabolite lactic acid that is a lactate in solution.
It is an anaerobic fermentation reaction, which takes place in certain kinds of bacteria and animal cells, like muscle cells.
