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. Salt in quantities of 2 – 5% in a brine or by weight of the produce being pickled.
