Cabbage + Microbes = Sauerkraut

Sauerkraut-making requires the bacteria Leuconostoc mesenteroides and Lactobacillus brevis to ferment sugars that provide a variety of such organic products as lactic acid, acetic acid, ethanol, and mannitol. These bacteria are known as ‘heterofermentative’ bacteria. Later a ‘homofermentative’ bacteria, Lactobacillus plantarum takes over, producing only lactic acid.
