The Leuconostocaceae is a family of Gram-positive bacteria, placed within the order of Lactobacillales. Representative genera include Leuconostoc, Oenococcus and Weissella. Bacteria that belongs to these three genera are Gram-positive, non-spore-forming, round or elongated in shape, are anaerobic or aerotolerant. They usually inhabit nutrient-rich environments such as milk, meat, vegetable products and fermented drinks (Björkroth & Holzapfel, 2006[1]). Lactic acid is the main end product of their characteristic heterofermentative carbohydrate metabolism. The phylogeny of the family of Leuconostocaceae has recently been evaluated by Chelo et al., 2007 [2]
