Many industrial compounds are byproducts of fungal fermentation. The exact mechanism of the lowering of E h when cheese is produced from milk is not clear but is probably related to the fermentation of lactose to lactic acid by the starter during growth. Fully cured sauerkraut keeps for several months in an airtight container stored at 15°C (60°F) or below. Fermentation is used in various industrial processes for the manufacture of products such as alcohols, acids, and cheese by the action of yeasts, molds, and bacteria.
