Heterofermentative bacteria produce one mole of lactate from one mole of glucose as well as CO2 and acetic acid or ethanol. Les objets ont-ils une histoire? With the increasing consumption of milk products these societies developed a lactase persistence by epigenetic inheritance, which means that the milk-digesting enzyme lactase was present in their body during the whole lifetime, so they could drink unfermented milk as adults too. Kimchi also uses lactic acid fermentation.

The bacteria also produce compounds that give yogurt its distinctive flavor. From Wikipedia, the free encyclopedia. Homolachic chemists discovered during the 19th century some fundamental concepts of the domain of organic chemistry.
Fatty acid degradation Beta oxidation Fatty acid synthesis. Therefore, even short-fermented milk contains enough enzymes to digest the lactose molecules, once the milk is in uomolactic human body, what allowed also adults to consume it.
