While there are a number of products from fermentation, the most common are ethanol, lactic acid, carbon dioxide, and hydrogen gas (H 2). In the first step, Glucose is converted to pyruvic acids through the glycolysis process. But it is an end product of. Production of this acid is commonly carried out by the lactic acid bacteria, Lactobacillus spps., for production of cheese, yogurt, sauerkraut, bread, and kefir, and for imparting a peculiar sour taste to such food items. When this happens, the regular pathway of cellular respiration is replaced by lactic acid fermentation in order to continue to provide energy to the muscle cells.

Lactic acid production starts with the fermentation of typically corn starch, cane sugar, or milk whey with, for example, lactic acid bacteria (LAB) or filamentous fungi. sucrose or lactose) are converted into cellular energy and the metabolite lactate, which is lactic acid in solution. Although the lactic acid fermentation equation must be written more clearly to make good sense. This plays to roles in the fermentation. Lactic acid fermentation converts the 3-carbon pyruvate to the 3-carbon lactic acid (C 3 H 6 O 3) (see Figure below) and regenerates NAD + in the process, allowing glycolysis to continue to make ATP in low-oxygen conditions.
