From [wikipedia] “Leuconostoc spp., along with other lactic acid bacteria such as Pediococcus and Lactobacillus, are responsible for the fermentation of cabbage, making it sauerkraut. In this process, fresh cabbage is fermented in a light brine, where the sugars in the cabbage are transformed by lactofermentation to lactic acid which gives the cabbage a sour flavour and good keeping qualities. Leuconostoc spp. are similarly part of the symbiotic colonies of bacteria and yeast or SCOBYinvolved in the fermentation of kefir, a fermented milk beverage.
